DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and/or" in the specification and claims represents at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The electronic device and control method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

The electronic device and control method provided in the embodiments of the present application can be applied to a scenario where the electronic device enters a transport mode, or to a scenario where the electronic device is shut down.

Scenarios for transport modes

In the related art, as shown in FIG. 1A , one end of a battery 01 of an electronic device may be connected to a switch tube QBAT on a main power management integrated circuit (PMIC) of a mainboard 02 to provide a voltage VBAT to the main PMIC of the mainboard 02, and one end of the switch tube QBAT may be connected to a plurality of slave PMICs, such as PMIC1, PMIC2, etc., and each slave PMIC may be connected to at least one device to provide a voltage VPH to the PMIC1, PMIC2, etc. Specifically, as shown in FIG1B , the battery 01 of the electronic device can be connected to the mainboard 02 through the protection integrated circuit 03 , and the p+ node in FIG1B can be understood as one end of the battery 01 connected to the switch tube QBAT on the main PMIC of the mainboard 02 , that is, the battery can provide the voltage VBAT to the main PMIC of the mainboard 02 through the p+ node, and the switch tube QBAT connected to one end of the battery 01 is set in the main PMIC of the mainboard 02 , and one end of the switch tube QBAT connected to multiple slave PMICs can be the VPH_PWR pin in FIG1B , and it can be understood that the VPH_PWR pin is connected to the multiple slave PMICs (the multiple slave PMICs are not shown in FIG1B ). In this way, when the electronic device is not used for a long time, the electronic device can be controlled to enter the shipping mode (Ship Mode) so that the mainboard 02 of the electronic device can control the switch tube QBAT to be disconnected to stop supplying power to the devices connected to the multiple slave PMICs through the VPH_PWR pin, thereby reducing the power consumption of the battery 01, so as to reduce the situation where the battery 01 has a low power for a long time, and then reduce the phenomenon of bulging of the battery 01, thereby improving the safety of the electronic device. However, in conjunction with Figure 1A, since one end of the battery 01 (for example, the p+ node) may be directly connected to other devices (for example, a fast charging integrated circuit, a near-field communication (NFC) module, etc.) to provide a voltage VBAT to the other devices, even if the switch tube QBAT in the main PMIC of the motherboard 02 is turned off, the battery 01 will still supply power to the above-mentioned other devices (i.e., the fast charging integrated circuit, the NFC module, etc.). As a result, the power of the battery 01 of the electronic device will continue to be consumed in the shipping mode. In this way, if the electronic device is not used for a long time, the battery 01 will still have a low power for a long time, which will cause the battery 01 to bulge, etc., thereby resulting in low safety of use of the electronic device.

In some embodiments of the present application, in combination with FIG. 2 , as shown in FIG. 3 , a main power management integrated circuit (PMIC) 104 may also be provided on the mainboard 10. The main PMIC 104 may include a third pin 1041, a VPH_PWR pin 1042, a GND pin 1043 and a VBUS pin 1044, wherein the third pin 1041 and the GND pin 1043 are used to connect to the battery 11, the VPH_PWR pin 1042 may be connected to a plurality of slave PMICs (the plurality of slave PMICs are not shown in FIG. 3 ) of the electronic device, each of the plurality of slave PMICs may be connected to at least one device, so that power may be supplied to at least one device connected to each slave PMIC through the main PMIC 104, and the VBUS pin 1044 is used to connect to an external power supply (such as the second power supply in the following embodiments) to supply power to the mainboard 10 through the external power supply, thereby charging the battery 11. The third pin 1041 may be specifically the first end of the mainboard 10 or the second end of the mainboard 10 , and the GND pin 1043 may be specifically the second end of the mainboard 10 or the first end of the mainboard 10 .

In some embodiments of the present application, the first power source 103 may be a long-duration power source, wherein the first power source 103 may provide a predetermined voltage, such as 1.8 volts v.

In the embodiment of the present application, the state of the above-mentioned first switch group 102 includes a first state and a second state. In the first state, the second end of the first switch group 102 is connected to the fourth end of the first switch group 103, so that the first power supply 103 provides a voltage to the first pin 121; in the second state, the third end of the first switch group 102 is connected to the fourth end of the first switch group 103, so that the first pin 121 is grounded.

In some embodiments of the present application, the first switch group 102 may include at least one switch tube, and at least some of the switch tubes in the at least one switch tube are of different models. In the first state, some of the switch tubes in the at least one switch tube are turned on, and the other switch tubes are turned off, so that the first power supply 103 and the first pin 121 are connected, so that the first power supply 103 can provide a voltage to the first pin 121; in the second state, some of the switch tubes are turned off, and the other switch tubes are turned off, so that the first pin 121 is grounded.

The following is an example in which the first switch group 102 includes two switch tubes.

In some embodiments of the present application, in combination with Figure 2, as shown in Figure 4, the above-mentioned first switch group 102 includes: a second switch tube 1021, a first end of the second switch tube 1021 is connected to the first controller 101, a second end of the second switch tube 1021 is connected to the first power supply 103, and a third end of the second switch tube 1021 is connected to the first pin 121; a third switch tube 1022, a first end of the third switch tube 1022 is connected to the first controller 101, a second end of the third switch tube 1022 is grounded, and a third end of the third switch tube 1022 is connected to the first pin 121.

It can be understood that the first end of the second switch tube 1021 is the first end of the first switch group 102 , the second end of the second switch tube 1021 is the second end of the first switch group 102 , and the third end of the second switch tube 1021 is the fourth end of the first switch group 102 .

In some embodiments of the present application, the second switch tube 1021 may be a P-channel Metal Oxide Semiconductor (PMOS) tube.

In some embodiments of the present application, the first end of the second switch tube 1021 may be a gate end, the second end of the second switch tube 1021 may be a source end, and the third end of the second switch tube 1021 may be a drain end.

It can be understood that the first end of the third switch tube 1022 is the first end of the first switch group 102 , the second end of the third switch tube 1022 is the third end of the first switch group 102 , and the third end of the third switch tube 1022 is the fourth end of the first switch group 102 .

In some embodiments of the present application, the third end of the third switch tube 1022 is also connected to the third end of the second switch tube 1021 .

In some embodiments of the present application, the third switch tube 1022 may be an N-Channel Metal Oxide Semiconductor (NMOS) tube, that is, the third switch tube 1022 is of a different model from the second switch tube 1021 .

In some embodiments of the present application, the first end of the third switch tube 1022 may be a gate end, the second end of the third switch tube 1022 may be a drain end, and the third end of the third switch tube 1022 may be a source end.

In the embodiment of the present application, in the first state, the second switch tube 1021 is turned on and the third switch tube 1022 is turned off; in the second state, the second switch tube 1021 is turned off and the third switch tube 1022 is turned on.

In some embodiments of the present application, when the first controller 101 outputs a low level, the second switch tube 1021 is turned on and the third switch tube 1022 is turned off, and the state of the first switch group 102 is the first state. At this time, the second end of the second switch tube 1021 and the third end of the second switch tube 1021 are turned on, that is, the path between the first power supply 103 and the first pin 121 is turned on. Therefore, the first power supply 103 can provide a voltage to the first pin 121, for example, the above-mentioned predetermined voltage 1.8v, so that the voltage of the first pin 121 is the same as the predetermined voltage, for example, the voltage of the first pin 121 is also 1.8v.

In some embodiments of the present application, when the first controller 101 outputs a high level, the second switch tube 1021 is disconnected and the third switch tube 1022 is turned on, and the state of the first switch group 102 is the second state. At this time, the second end of the third switch tube 1022 and the third end of the third switch tube 1022 are turned on, that is, the path between the first pin 121 and the ground end is turned on, therefore, the first pin 121 is grounded, and the voltage of the first pin 121 becomes 0v.

It can be understood that in the first state, the voltage of the first pin 121 is different from the voltage of the first pin 121 in the second state.

Thus, it can be known that since the first switch group can be provided with the second switch tube and the third switch tube, the first controller can simultaneously control the second switch tube to be turned on or off, and control the third switch tube to be turned off or on, so that the state of the first switch group can be the first state or the second state. That is, only the second switch tube and the third switch tube need to be provided, and the first controller can control the first switch group to switch between the first state and the second state without providing more switch tubes. Therefore, the circuit complexity of the mainboard can be reduced while the cost of the mainboard can be reduced, thereby reducing the circuit complexity of the electronic device while reducing the cost of the electronic device.

In some embodiments of the present application, the first controller 101 may be any one of the following: an application processor (AP), a microcontroller unit (MCU). Of course, the first controller 101 may also be other processors, which are not limited in the embodiments of the present application.

In the embodiment of the present application, the first controller 101 is used to control the first switch group 102 to switch between the first state and the second state when the path between the battery 11 and the mainboard 10 is conductive, so as to generate a first voltage signal at the first pin 121.

It can be understood that the first controller 101 is used to control the first switch group 102 to switch between the first state and the second state when the battery 11 supplies power to the mainboard 10 , so as to generate a first voltage signal at the first pin 121 .

In some embodiments of the present application, when the path between the battery 11 and the mainboard 10 is conductive, the first controller 101 may control the first switch group 102 to switch between the first state and the second state if it is determined that the ship mode needs to be entered.

Among them, the first controller 101 can determine that it is necessary to enter the Ship Mode when the path between the battery 11 and the main board 10 is connected and a predetermined operation of the user on the electronic device is received; or, it can determine that it is necessary to enter the Ship Mode when the path between the battery 11 and the main board 10 is connected and the voltage of the battery 11 is less than or equal to a certain threshold (for example, the low voltage protection threshold in the following embodiment).

Here, the predetermined operation may be any of the following: an operation performed by a user on a display screen of an electronic device, an operation performed by a user on a physical key of an electronic device, etc. Of course, the predetermined operation may also be other operations, which are not limited in the present embodiment.

Here, the first controller 101 may determine that it is necessary to enter the ship mode when the voltage of the battery 11 is less than or equal to a certain threshold when the path between the battery 11 and the mainboard 10 is conductive and the electronic device is in the power-on state (or power-off state).

In some embodiments of the present application, when the path between the battery 11 and the mainboard 10 is turned on, the first controller 101 may first control the state of the first switch group 102 to be the first state, at which time the first power supply 103 may provide a voltage to the first pin 121, so that when it is determined that the ship mode needs to be entered, the first controller 101 may first control the state of the first switch group 102 to be the second state, and then control the state of the first switch group 102 to be the first state, and so on, to control the first switch group 102 to switch back and forth between the first state and the second state, so as to generate a first voltage signal at the first pin 121.

It can be understood that, since in the first state, the first power supply 103 can provide the above-mentioned predetermined voltage to the first pin 121, the voltage of the first pin 121 can be the above-mentioned predetermined voltage at this time, and in the second state, the first pin 121 is grounded, at this time the voltage of the first pin 121 can be changed from the above-mentioned predetermined voltage to 0v, therefore, the first switch group 102 switches back and forth between the first state and the second state, and can generate a pulse voltage signal, i.e., a first voltage signal, at the first pin 121.

In some embodiments of the present application, the battery 11 may be any of the following: a lithium battery, a silicon negative electrode battery, a steel shell battery. Of course, the battery 11 may also be other batteries, which are not limited in the embodiments of the present application.

In some embodiments of the present application, the first electrode of the battery 11 may be a positive electrode or a negative electrode. The second electrode of the battery 11 may be a negative electrode or a positive electrode. It should be noted that FIG. 2 illustrates that the first electrode of the battery 11 is a positive electrode and the second electrode of the battery 11 is a negative electrode.

In the embodiment of the present application, the first integrated circuit 12 is used to control the first switch tube 122 to be disconnected according to the first voltage signal, so as to disconnect the path between the battery 11 and the mainboard 10.

It can be understood that the first integrated circuit 12 is used to control the first switch tube 122 to be disconnected according to the first voltage signal, so that the battery 11 stops supplying power to the mainboard 10 .

It can be understood that if the first integrated circuit 12 receives the first voltage signal, it can be considered that it may be necessary to enter the shipping mode. Therefore, the first integrated circuit 12 can directly control the first switch tube 122 to disconnect to disconnect the path between the battery 11 and the mainboard 10.

In some embodiments of the present application, the first integrated circuit 12 may be a protection integrated circuit. The first integrated circuit 12 may include a plurality of pins, such as a VDD pin, a VSS pin, a VS pin, a DOUT pin, a COUT pin, a VM pin, and a first pin 121. The VDD pin is connected to the positive electrode of the battery 11, the VSS pin is connected to the negative electrode of the battery 11, the DOUT pin is connected to the first switch tube 122, and the first pin 121 may be a CTL pin.

It should be noted that for the description of the functions of the VDD pin, VSS pin, VS pin, DOUT pin, COUT pin and VM pin, reference can be made to the specific description in the relevant technology, and the embodiments of the present application will not be repeated here.

Exemplarily, assuming that the first pole of the battery 11 is a positive pole and the second pole of the battery 11 is a negative pole, in combination with FIG. 2, FIG. 3 and FIG. 4, the first pole (i.e., the positive pole) of the battery 11 is connected to the first end (e.g., the third pin 1041) of the mainboard 10, the VDD pin can be connected to the first pole of the battery 11 through the resistor R1, the VSS pin can be connected to the second pole (i.e., the negative pole) of the battery 11, the CS pin can be connected to the second pole of the battery 11 through the resistor RSNS, the DOUT pin can be connected to the gate of the first switch tube 122, the source of the first switch tube 122 can be connected to the resistor RSNS, and COUT The pin can be connected to the gate of the fourth switch tube Q1, the source of the fourth switch tube Q1 can be connected to the drain of the first switch tube 122, and the drain of the fourth switch tube Q1 can be connected to the second end of the mainboard 10 (for example, the GND pin 1043). It can be understood that in Figures 2, 3 and 4, the second electrode of the battery 11 is connected to the second end of the mainboard 10 (for example, the GND pin 1043) through the resistor RSNS, the first switch tube 122 and the fourth switch tube Q1, and the VM pin can be connected to the drain of the fourth switch tube Q1 and the second end of the mainboard 10 (for example, the GND pin 1043) through the resistor R2.

As another example, assuming that the first electrode of the battery 11 is a negative electrode and the second electrode of the battery 11 is a positive electrode, as shown in FIG5 , the first electrode (i.e., the negative electrode) of the battery 11 is connected to the first end (e.g., the GND pin 1043) of the mainboard 10, the VDD pin can be connected to the second electrode (i.e., the positive electrode) of the battery 11, the VSS pin can be connected to the first electrode (i.e., the negative electrode) of the battery 11 through the resistor R1, the CS pin can be connected to the second electrode (i.e., the positive electrode) of the battery 11 through the resistor RSNS, the DOUT pin can be connected to the gate of the first switch tube 122, and the source of the first switch tube 122 can be connected to the drain of the fourth switch tube Q1. The drain of the first switch tube 122 can be connected to the second end of the mainboard 10 (for example, the third pin 1041), the COUT pin can be connected to the gate of the fourth switch tube Q1, and the source of the fourth switch tube Q1 is connected to the resistor RSNS and the CS pin. It can be understood that in Figure 5, the second pole (i.e., the positive pole) of the battery 11 is connected to the second end of the mainboard 10 (for example, the third pin 1041) through the resistor RSNS, the fourth switch tube Q1 and the first switch tube 122, and the VM pin can be connected to the drain of the first switch tube 122 and the second end of the mainboard 10 (for example, the third pin 1041) through the resistor R2.

In some embodiments of the present application, the first integrated circuit 12 can directly control the first switch tube 122 to disconnect when receiving the first voltage signal, or, when receiving the first voltage signal, it can first determine whether the first voltage signal satisfies a certain condition (such as the first condition in the following embodiment), and then control the first switch tube 122 to disconnect when the first voltage signal satisfies the certain condition.

Among them, the first integrated circuit 12 can delay the fourth time period before controlling the first switch tube 122 to disconnect when receiving the first voltage signal, or can delay the fourth time period before controlling the first switch tube 122 to disconnect when receiving the first voltage signal and the first voltage signal meets the certain condition.

The following will take the case where the first integrated circuit 12 needs to determine whether the first voltage signal satisfies a certain condition to determine whether to control the first switch tube 122 to be turned off as an example for explanation.

In the embodiment of the present application, the above-mentioned first controller 101 is specifically used to control the first switch group 102 to switch back and forth between the first state and the second state according to the first quantity within a first time period, and the time interval between the switching times of two adjacent switches is greater than or equal to the second time period, so as to generate a first voltage signal at the first pin 121.

In some embodiments of the present application, the first number may be 5. Of course, the first number may also be other numbers, which is not limited in the embodiments of the present application.

Exemplarily, assuming that the first number is 5, the first controller 101 can first switch the state of the first switch group 102 from the first state to the second state within a first time period, and then switch the state of the first switch group 102 from the second state to the first state after a second time period from the moment of switching to the second state, so as to complete the reciprocating switching of the first switch group 102 between the first state and the second state once. Next, the first controller 101 can repeat the above steps four times to complete the reciprocating switching of the first switch group 102 between the first state and the second state four times, so as to generate a first voltage signal at the first pin 121.

In the embodiment of the present application, the above-mentioned first integrated circuit 12 is specifically used to control the first switch tube 122 to disconnect when the first voltage signal meets the first condition; the first condition includes: the number of pulses of the first voltage signal within the first time length is a first number, and the pulse duration of each pulse is greater than or equal to the second time length.

In the embodiment of the present application, since the first controller 101 or PMIC 104 may be interfered with, causing the voltage of the first pin 122 to change, this may cause the first integrated circuit 12 to directly control the first switch tube 122 to be disconnected. Therefore, in order to avoid the above situation, the first controller 101 can control the on and off of the first switch tube 122 according to the above method to generate a specific sequence of pulse voltage signals (i.e., the first voltage signal), and the first integrated circuit 12 will control the first switch tube 122 to be disconnected only when the first voltage signal meets the first condition.

It can be understood that after the first integrated circuit 12 controls the first switch tube 122 to be turned off, the electronic device can enter the shipping mode.

The following is a specific example to illustrate the process of electronic equipment entering shipping mode.

In combination with FIG. 2 , FIG. 3 and FIG. 4 , as shown in FIG. 6 , the electronic device is in a normal state (for example, the path between the battery 11 and the mainboard 10 is connected, and the electronic device is in a power-on state or a power-off state), the first controller 101 can first control the state of the first switch group 102 to be the first state, at which time the first power supply 103 can provide the above-mentioned predetermined voltage 1.8v to the first pin 121, so that the voltage of the first pin 121 is maintained at 1.8v, that is, the voltage signal (for example, CTL signal) of the first pin 121 is maintained at 1.8v, and when it is determined that the Ship mode needs to be entered, the first power supply 103 can provide the first pin 121 with the predetermined voltage 1.8v. In the case of a first switching mode, the first controller 101 can first control the state of the first switch group 102 to switch from the first state to the second state within a first time length (for example, T2), at which time the first pin 121 is grounded, so that the voltage of the first pin 121 changes from 1.8v to 0v, and then after a second time length (for example, T1) from the moment of switching to the second state, the state of the first switch group 102 is switched from the second state to the first state, at which time the first power supply 103 can provide the first pin 121 with the above-mentioned predetermined voltage 1.8v, so that the voltage of the first pin 121 can change from 0v to 1.8v, so as to complete the first switching mode. The switch group 102 switches back and forth between the first state and the second state once, and then the first controller 101 can repeat the above steps four times to complete the switching of the first switch group 102 between the first state and the second state four times, so that the first voltage signal as shown in Figure 6 can be generated at the first pin 121, and then the first integrated circuit 12 can control the first switch tube 122 to disconnect after delaying for a fourth time period (for example, T3) when it is determined that the number of pulses of the first voltage signal within the first time period is the first number (i.e., 5) and the pulse duration of each pulse is greater than or equal to the second time period (i.e., T2), that is, the electronic device enters the shipping mode.

Thus, it can be known that, when it is necessary to disconnect the passage between the battery and the mainboard, the first controller can control the first switch group to switch back and forth between the first state and the second state according to the first quantity within a first time period, and the time interval between the switching times of two adjacent switches is greater than or equal to the second time period to generate a first voltage signal that satisfies the first condition. In this way, the first integrated circuit can disconnect the passage between the battery and the mainboard according to the first voltage signal that satisfies the first condition, rather than disconnecting the passage between the battery and the mainboard according to an arbitrary signal. Therefore, it is possible to avoid the situation where the passage between the battery and the mainboard is disconnected due to interference. In this way, it is possible to avoid the situation where the battery supplies power to the mainboard due to interference.

It should be noted that the first controller 101 can also control the first switch group 102 to switch back and forth between the first state and the second state in other ways to generate a first voltage signal that meets other conditions at the first pin 121, which is not limited in this embodiment of the present application.

In the related art, when it is necessary to disconnect the path between the battery 11 and the mainboard 10, only the switch tube QBAT in the main PMIC 104 is disconnected, so that the device connected to the VPH_PWR pin 1042 of the main PMIC 104 is powered off, but the device directly connected to the p+ node of the battery 11 is still in a working state, that is, the battery 11 still supplies power to the device, thus causing the battery 11 to continue to consume power. However, in the embodiment of the present application, when it is necessary to disconnect the path between the battery 11 and the mainboard 10, the first switch tube 122 can be disconnected, so that the path between the battery 11 and the mainboard 10 is disconnected, and at this time, the VPH_PWR1042 pin of the main PMIC 104 and the device directly connected to the p+ node of the battery 11 are powered off, thus reducing the battery power consumption.

An embodiment of the present application provides an electronic device, which includes a mainboard provided with a first controller, a first switch group and a first power source, a battery having a first pole connected to a first end of the mainboard, and a first integrated circuit including a first pin and a first switch tube, wherein the first end of the first switch group is connected to the first controller, the second end of the first switch group is connected to the first power source, the third end of the first switch group is grounded, the first pin is connected to the fourth end of the first switch group, and the second pole of the battery is connected to the second end of the mainboard through the first switch tube; wherein the state of the first switch group includes a first state and a second state, wherein in the first state, the second end of the first switch group is connected to the fourth end of the first switch group, so that the first power source provides a voltage to the first pin; and in the second state, the third end of the first switch group is connected to the fourth end of the first switch group, so that the first pin is grounded; the first controller is used to control the first switch group to switch between the first state and the second state when the path between the battery and the mainboard is connected, so as to generate a first voltage signal at the first pin; and the first integrated circuit is used to control the first switch tube to be disconnected according to the first voltage signal, so as to disconnect the path between the battery and the mainboard. Since the battery is provided with a first switch tube and a first integrated circuit, and the mainboard is provided with a first controller, a first switch group and a first power supply, the first controller can make the first pin switch between being connected to the first power supply and being grounded by adjusting the way of controlling the first switch group to switch between different states when the path between the battery and the mainboard is connected, that is, when the battery supplies power to the mainboard. In this way, a first voltage signal can be generated on the first pin to trigger the first integrated circuit to control the first switch tube to disconnect through the first voltage signal, so as to disconnect the path between the battery and the mainboard, so that the battery stops supplying power to the mainboard, thereby stopping supplying power to all devices of the electronic device, rather than stopping supplying power to some devices of the electronic device. Therefore, the number of battery-powered devices can be reduced to reduce the power consumption of the battery, so as to reduce the situation where the battery has a low power for a long time when the electronic device is not used for a long time, and further reduce the phenomenon of battery bulging, etc., so that the safety of the use of the electronic device can be improved.

Of course, after disconnecting the path between the battery 11 and the mainboard 10, the first integrated circuit 12 can also conduct the path between the battery 11 and the mainboard 10 when it is determined that the user needs to use the electronic device. Optionally, in combination with FIG. 2, as shown in FIG. 7, the first integrated circuit 12 further includes a second pin 123, and the second pin 123 is connected to the second end of the mainboard 10; the first integrated circuit 12 is also used to adjust the voltage of the second pin 123 to a preset voltage when the path between the battery 11 and the mainboard 10 is disconnected.

In some embodiments of the present application, the second pin 123 may be a VM pin. In FIG7 , the first pole of the battery 11 is a positive pole, the second pole of the battery 11 is a negative pole, and the second pin 123 may be connected to the second end of the motherboard 10 (e.g., the GND pin 1043). In FIG8 , the first pole of the battery 11 is a negative pole, the second pole of the battery 11 is a positive pole, and the second pin 123 may be connected to the second end of the motherboard 10 (e.g., the third pin 1041).

In some embodiments of the present application, the preset voltage may be the same as or different from the predetermined voltage. For example, the preset voltage may be 1.8V, that is, the preset voltage may be the same as the predetermined voltage.

In some embodiments of the present application, a fifth switch tube may be further provided in the first integrated circuit 12, and the second pin 123 may be connected to the VDD pin of the first integrated circuit 12 through the fifth switch tube, so that the first integrated circuit 12 may control the fifth switch tube to be turned on when the path between the battery 11 and the mainboard 10 is disconnected, so that the VDD pin may provide a voltage to the second pin 123. It can be understood that the preset voltage may be that the VDD pin may provide a voltage to the second pin 123. Alternatively, a sixth switch tube may be provided in the first integrated circuit 12, and the second pin 123 may be grounded through the sixth switch tube, so that the first integrated circuit 12 may control the sixth switch tube to be turned on when the path between the battery 11 and the mainboard 10 is disconnected, so that the second pin 123 may be grounded. It can be understood that the preset voltage may be 0v at this time.

Wherein, when the first integrated circuit 12 can conduct the path between the battery 11 and the mainboard 10, and the electronic device is in the power-on state or the power-off state, the fifth switch tube is controlled to be disconnected, so that the voltage of the second pin 123 can be at a low level. When the first integrated circuit 12 can conduct the path between the battery 11 and the mainboard 10, and the electronic device is in the power-on state or the power-off state, the sixth switch tube is controlled to be disconnected, so that the voltage of the second pin 123 can be at a low level.

In the embodiment of the present application, when the path between the second power source and the mainboard 10 is connected, the second end of the mainboard 10 is used to adjust the voltage of the second pin 123 to generate a second voltage signal at the second pin 123 .

In some embodiments of the present application, the second power supply may specifically be an external power supply. When a user needs to use an electronic device, the user may insert a plug of the second power supply into a charging port of the electronic device to enable a path between the second power supply and the mainboard 10 to be connected, so that the second end of the mainboard 10 may adjust the voltage of the second pin 123.

In some embodiments of the present application, when the path between the second power supply and the mainboard 10 is disconnected, the mainboard 10 is powered off, and the second pin 123 can be considered to be suspended. Therefore, the voltage of the second pin 123 is maintained at the above-mentioned preset voltage.

Assuming that the first pole of the battery 11 is the positive pole, the second pole of the battery 11 is the negative pole, and the second end of the mainboard 10 is the above-mentioned GND pin 1043, in conjunction with FIG7, when the path between the second power supply and the mainboard 10 is connected and the electronic device is in the power-on state (or the power-off state), the first integrated circuit 12 can control the fifth switch tube to be disconnected so that the voltage of the second pin 123 (i.e., the VM pin) can be 0v, and when the path between the battery 11 and the mainboard 10 is disconnected, the first integrated circuit 12 can control the fifth switch tube to be turned on so that the VDD pin can provide the above-mentioned preset voltage to the second pin 123. The user can control the conduction of the path between the second power supply and the mainboard 10 so that the mainboard 10 is powered on, so that the current can flow from the second power supply through the VBUS pin 1044 (i.e., the pin connecting the second power supply to the mainboard 10), the VPH_PWR pin 1042, the switch tube QBAT, the P+ node, the first pole (i.e., the positive pole) of the battery 11, the second pole (i.e., the negative pole) of the battery 11, the resistor RSNS, the first switch tube 122, the fourth switch tube Q1 and the p-node to the GND pin 1043. At this time, the second pin 123 can be regarded as grounded, so the voltage of the second pin 123 changes from the above-mentioned preset voltage to 0v.

It should be noted that, since one end of the first switch tube 122 connected to the second pole of the battery 11 can also be connected to the other end of the first switch tube 122 and the GND pin 1043 through a diode, the positive pole of the diode is connected to one end of the first switch tube 122, and the negative pole of the diode is connected to the other end of the first switch tube 122. Therefore, when the first switch tube 122 is disconnected, the current can still flow to the fourth switch tube Q1 through one end of the first switch tube 122, the diode and the other end of the first switch tube 122.

Assuming that the first pole of the battery 11 is a negative pole, the second pole of the battery 11 is a positive pole, and the second end of the mainboard 10 is the third pin 1041 mentioned above, in conjunction with Figure 8, when the path between the second power supply and the mainboard 10 is connected and the electronic device is in the power-on state (or the power-off state), the first integrated circuit 12 can control the sixth switch tube to be disconnected, and when the path between the battery 11 and the mainboard 10 is disconnected, the first integrated circuit 12 can control the sixth switch tube to be turned on, so that the second pin 123 (for example, the VM pin) is grounded, and the second pin 123 is the above-mentioned preset voltage (that is, 0v). At this time, the user can control the path between the second power supply and the mainboard 10 to be connected, so that the mainboard 10 is powered on, so that the current can flow from the second power supply through the VBUS pin 1044 (that is, the pin connecting the second power supply to the mainboard 10), the VPH_PWR pin 1042, the switch tube QBAT, and the P+ node to the second pin 123. At this time, the second pin 123 can be regarded as provided with voltage by the second power supply. Therefore, the power supply of the second pin 123 is changed from the above-mentioned preset power supply (for example, 0V) to the voltage provided by the second power supply (for example, 1.8v).

In the embodiment of the present application, the first integrated circuit 12 is further used to control the first switch tube 122 to be turned on according to the second voltage signal, so as to conduct the path between the battery 11 and the mainboard 10 .

In some embodiments of the present application, the first integrated circuit 12 can directly control the first switch tube 122 to be turned on when receiving the second voltage signal, or, when receiving the second voltage signal, it can first determine whether the second voltage signal satisfies a certain condition (such as the second condition in the following embodiment), and then control the first switch tube 122 to be turned on when the second voltage signal satisfies the certain condition.

Thus, it can be known that when the path between the battery and the mainboard needs to be opened, that is, when the battery needs to supply power to the mainboard, the second power supply can be used to supply power to the mainboard, so that the second end of the mainboard adjusts the voltage of the second pin to generate a second voltage signal at the second pin. Therefore, the first integrated circuit can accurately control the conduction of the first switch tube through the second voltage signal to accurately open the path between the battery and the mainboard.

The following will take the case where the first integrated circuit 12 needs to determine whether the second voltage signal satisfies a certain condition to determine whether to control the first switch tube 122 to be turned on as an example for explanation.

In some embodiments of the present application, the above-mentioned first integrated circuit 12 is specifically used to control the first switch tube 122 to be turned on when the second voltage signal satisfies a second condition; the second condition includes: the voltage corresponding to the second voltage signal changes once, and the voltage corresponding to the second voltage signal does not change within a third time period.

In the embodiment of the present application, since the voltage of the second pin 123 may change due to interference with the first controller 101 or PMIC 104, the first integrated circuit 12 may directly control the first switch tube 122 to be turned on. Therefore, in order to avoid the above situation, the user can use the above method to supply power to the mainboard 10 with the second power supply to generate a specific sequence of pulse voltage signals (i.e., the second voltage signal), and the first integrated circuit 12 will control the first switch tube 122 to be turned on only when the second voltage signal satisfies the second condition.

It can be understood that after the first integrated circuit 12 controls the first switch tube 122 to be turned on, the electronic device can exit the shipping mode.

The following will use a specific example to illustrate the process of an electronic device exiting shipping mode.

In combination with FIG. 7 , as shown in FIG. 9 , the electronic device is in the power-on state or the power-off state, and the path between the battery 11 and the mainboard 10 is connected, the first integrated circuit 12 can control the fifth switch tube to be disconnected, so that the second pin 123 is grounded, and the voltage of the second pin 123 is 0v. When the path between the battery 11 and the mainboard 10 is disconnected, that is, when the electronic device enters the shipping mode, the first integrated circuit 12 can control the fifth switch tube to be turned on, so that the VDD pin can provide the above-mentioned preset voltage, such as 1.8v, to the second pin 123 (such as the VM pin), and the voltage of the second pin 123 changes from 0v to 1.8v. Thus, when the user needs to use the electronic device, the user can control the path between the second power supply and the mainboard 10 to be turned on for a third time period so that the mainboard 10 is powered on, so that the second pin 123 can be regarded as grounded, and the voltage of the second pin 123 changes from 1.8v to 0v, and the voltage of the second pin 123 does not change within the third time period, so as to generate a second voltage signal (such as a VM signal) that meets the second condition on the second pin 123. At this time, the first integrated circuit 12 can turn on the path between the battery 11 and the mainboard 10, so that the electronic device exits the ship mode.

It can be seen that when it is necessary to conduct the path between the battery and the mainboard, that is, when it is necessary to control the battery to continue to supply power to the mainboard, the second power supply can be controlled to supply power to the mainboard according to the third duration to generate a second voltage signal that satisfies the second condition. In this way, the first integrated circuit can conduct the path between the battery and the mainboard according to the second voltage signal that satisfies the second condition, rather than conducting the path between the battery and the mainboard according to an arbitrary signal. Therefore, it can be avoided that the path between the battery and the mainboard is conducted due to interference. In this way, it can be avoided that the battery supplies power to the mainboard due to interference.

Of course, in order to further avoid the situation where the battery 11 has a low power for a long time, the electronic device can control the first switch group 102 to switch between the first state and the second state when the voltage of the battery 11 is less than or equal to a threshold (for example, the low voltage protection threshold in the following embodiment) to disconnect the path between the battery 11 and the mainboard 10. Optionally, the first controller 101 is specifically used to control the first switch group 102 to switch between the first state and the second state when the path between the battery 11 and the mainboard 10 is connected and the voltage of the battery 11 is less than or equal to the low voltage protection threshold.

In some embodiments of the present application, the low voltage protection threshold may be a preconfigured threshold or a threshold set by a user.

It should be noted that, for the description of the first controller 101 controlling the first switch group 102 to switch between the first state and the second state, reference may be made to the specific description in the above embodiment, which will not be repeated herein in the embodiment of the present application.

It can be seen that since the first controller can control the first switch group to switch between the first state and the second state when the path between the battery and the mainboard is turned on and the battery voltage is less than or equal to the low voltage protection threshold, it can trigger the first integrated circuit to control the first switch tube to disconnect, and then disconnect the path between the battery and the mainboard. Therefore, the situation where the battery has low power for a long time can be reduced, thereby reducing the occurrence of battery bulging and other phenomena. In this way, the safety of electronic equipment can be improved.

In some embodiments of the present application, the above-mentioned first integrated circuit 12 is also used to adjust the threshold value of the low voltage protection threshold from the initial threshold value to the first threshold value when the path between the battery 11 and the main board 10 is connected and the electronic device is in the power-on state; or, it is also used to adjust the threshold value of the low voltage protection threshold from the initial threshold value to the second threshold value when the path between the battery 11 and the main board 10 is connected and the electronic device is in the power-off state.

In the embodiment of the present application, the first threshold value is smaller than the initial threshold value, and the second threshold value is larger than the initial threshold value.

In some embodiments of the present application, the first threshold value may be a preconfigured threshold value or a threshold value set by a user. The first threshold value may specifically be 2.3 V. Of course, the first threshold value may also be other threshold values, which are not limited in the embodiments of the present application.

In the embodiment of the present application, when the electronic device is in the power-on state and the battery 11 has a low power level, if the electronic device is performing a high-load task, the voltage of the battery 11 may be lower than the above-mentioned initial threshold value. At this time, the electronic device may be directly shut down. Therefore, in order to avoid the above-mentioned situation, the first integrated circuit 12 can lower the threshold value of the low-voltage protection threshold when the path between the battery 11 and the mainboard 10 is conductive and the electronic device is in the power-on state, thereby reducing the situation where the voltage of the battery 11 is lower than the first threshold value during the execution of high-load tasks.

In some embodiments of the present application, the second threshold value may be a preconfigured threshold value or a threshold value set by a user. The second threshold value may specifically be 2.6 V. Of course, the second threshold value may also be other threshold values, which are not limited in the embodiments of the present application.

In the embodiment of the present application, since it can be considered that the user does not need to use the electronic device when the electronic device is in the off state, in order to save battery power, the first integrated circuit 12 can increase the threshold value of the low-voltage protection threshold when the path between the battery 11 and the mainboard 10 is connected and the electronic device is in the off state, so as to further reduce the battery power consumption, thereby reducing the situation where the battery is low in power for a long time.

Thus, it can be known that, since the first integrated circuit can lower the threshold value of the low voltage protection threshold when the path between the battery and the mainboard is conductive and the electronic device is in the power-on state, that is, the first integrated circuit can lower the threshold value of the low voltage protection threshold when the user needs to use the electronic device, it can reduce the situation that the electronic device is shut down due to the battery voltage being lower than the first threshold value during the execution of high-load tasks, thereby reducing the situation that the user cannot use the electronic device normally when the user needs to use the electronic device. Alternatively, the first integrated circuit can raise the threshold value of the low voltage protection threshold when the path between the battery and the mainboard is conductive and the electronic device is in the power-off state, that is, the first integrated circuit can raise the threshold value of the low voltage protection threshold when the user does not need to use the electronic device, thereby further reducing the power consumption of the battery, thereby reducing the situation that the battery power is low for a long time.

Fig. 10 shows a flow chart of a control method provided in an embodiment of the present application, which is applied to the electronic device in the above embodiment. As shown in Fig. 10, the control method provided in an embodiment of the present application may include the following steps 101 and 102.

Step 101: When a path between a battery of an electronic device and a mainboard of the electronic device is connected, the electronic device controls a first switch group of the mainboard of the electronic device to switch between a first state and a second state through a first controller of the mainboard, so as to generate a first voltage signal at a first pin of a first integrated circuit of the electronic device.

In the embodiment of the present application, the state of the above-mentioned first switch group includes a first state and a second state. In the first state, the first power supply of the mainboard provides voltage to the first pin; in the second state, the first pin is grounded.

In some embodiments of the present application, when the electronic device is in the power-on state or the power-off state, the electronic device can conduct the path between the battery of the electronic device and the motherboard of the electronic device, and the electronic device can determine in real time whether to enter the ship mode (Ship Mode), so that when the electronic device determines that it has entered the ship mode, the electronic device can control the first switch group to switch between the first state and the second state through the first controller to generate a first voltage signal at the first pin.

It should be noted that for the description of the electronic device controlling the first switch group to switch between the first state and the second state through the first controller to generate a first voltage signal on the first pin, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

Step 102: The electronic device controls the first switch tube of the first integrated circuit to disconnect according to the first voltage signal through the first integrated circuit, so as to disconnect the path between the battery and the mainboard.

In some embodiments of the present application, the above step 101 can be specifically implemented through the following step 101a.

Step 101a, when the path between the battery of the electronic device and the mainboard of the electronic device is turned on, the electronic device controls the first switch group to switch back and forth between the first state and the second state according to the first quantity within a first time period through the first controller, and the time interval between the switching times of two adjacent switches is greater than or equal to the second time period, so as to generate a first voltage signal at the first pin of the first integrated circuit of the electronic device.

Step 102a: When the first voltage signal satisfies the first condition, the electronic device controls the first switch tube to be turned off according to the first voltage signal through the first integrated circuit.

In the embodiment of the present application, the first condition includes: the number of pulses of the first voltage signal within the first duration is a first number, and the pulse duration of each pulse is greater than or equal to the second duration.

In an embodiment of the present application, since the voltage of the first pin may change due to interference with the first controller or PMIC, this may cause the first integrated circuit to directly control the first switch tube to be disconnected. Therefore, in order to avoid the above situation, the first controller can control the on and off of the first switch tube according to the above method to generate a specific sequence of pulse voltage signals (i.e., the first voltage signal), and the first integrated circuit will control the first switch tube to be disconnected only when the first voltage signal meets the first condition.

It can be understood that after the first integrated circuit controls the first switch tube to turn off, the electronic device can enter the shipping mode.

Thus, it can be known that, when it is necessary to disconnect the path between the battery and the mainboard, the first controller can control the first switch group to switch back and forth between the first state and the second state according to the first quantity within a first time period, and the time interval between the switching times of two adjacent switches is greater than or equal to the second time period to generate a first voltage signal that satisfies the first condition. In this way, the first integrated circuit can disconnect the path between the battery and the mainboard according to the first voltage signal that satisfies the first condition, rather than disconnecting the path between the battery and the mainboard according to an arbitrary signal. Therefore, it is possible to avoid the situation where the path between the battery and the mainboard is disconnected due to interference. In this way, it is possible to avoid the situation where the battery supplies power to the mainboard due to interference.

In the related art, when it is necessary to control the battery to stop supplying power to the mainboard, only the switch tube QBAT in the main PMIC will be disconnected, so that the device connected to the VPH_PWR pin of the main PMIC is powered off, but the device directly connected to the p+ node of the battery is still in working state, that is, the battery will still supply power to the device, thus causing the battery power to continue to be consumed. However, in the embodiment of the present application, when it is necessary to disconnect the path between the battery and the mainboard, that is, when it is necessary to stop the battery from supplying power to the mainboard, the first switch tube can be disconnected, so that the path between the battery and the mainboard can be disconnected, that is, the battery will stop supplying power to the mainboard, at this time, the VPH_PWR pin of the main PMIC and the device directly connected to the p+ node of the battery will be powered off, thus reducing the battery power consumption.

An embodiment of the present application provides a control method, in which, when a path between a battery of an electronic device and a mainboard of the electronic device is connected, the electronic device can control a first switch group of the mainboard of the electronic device to switch between a first state and a second state through a first controller of the mainboard, so as to generate a first voltage signal at a first pin of a first integrated circuit of the electronic device, so that the electronic device can control the first switch tube of the first integrated circuit to disconnect according to the first voltage signal through the first integrated circuit, so as to disconnect the path between the battery and the mainboard; wherein, the state of the above-mentioned first switch group includes a first state and a second state, in the first state, the first power supply of the mainboard provides voltage to the first pin; in the second state, the first pin is grounded. Since when the path between the battery and the mainboard is connected, that is, when the battery supplies power to the mainboard, the electronic device can adjust the way in which the first switch group switches between different states to generate a first voltage signal on the first pin, so as to trigger the first integrated circuit to control the first switch tube to disconnect through the first voltage signal, so as to disconnect the path between the battery and the mainboard, so that the battery stops supplying power to the mainboard, thereby stopping supplying power to all devices of the electronic device, rather than stopping supplying power to some devices of the electronic device. Therefore, the number of battery-powered devices can be reduced to reduce the power consumption of the battery, which can reduce the situation where the battery has a low power for a long time when the electronic device is not used for a long time, and further reduce the occurrence of battery bulging and the like, so that the safety of electronic equipment can be improved.

In some embodiments of the present application, after the above step 102, the control method provided by the embodiment of the present application may further include the following steps 201 and 202.

Step 201: When the path between the second power source and the mainboard is connected, the electronic device adjusts the voltage of the second pin through the second end of the mainboard to generate a second voltage signal at the second pin.

It should be noted that, for the description of the electronic device adjusting the voltage of the second pin through the second end of the motherboard to generate a second voltage signal at the second pin, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

Step 202: The electronic device controls the first switch tube to conduct according to the second voltage signal through the first integrated circuit to conduct the path between the battery and the mainboard.

Thus, it can be known that when it is necessary to conduct the path between the battery and the mainboard, that is, when it is necessary to control the battery to supply power to the mainboard, the second power supply can be used to supply power to the mainboard, so that the second end of the mainboard adjusts the voltage of the second pin to generate a second voltage signal at the second pin. Therefore, the first integrated circuit can accurately control the conduction of the first switch tube through the second voltage signal to accurately conduct the path between the battery and the mainboard.

In some embodiments of the present application, the duration of the conduction between the second power supply and the mainboard is a third duration. Optionally, the step 202 can be implemented by the following step 202a.

Step 202a: When the second voltage signal satisfies the second condition, the electronic device controls the first switch tube of the first integrated circuit to turn on according to the second voltage signal through the first integrated circuit.

In the embodiment of the present application, the second condition includes: the voltage corresponding to the second voltage signal changes once, and the voltage corresponding to the second voltage signal does not change within the third time period.

In the embodiment of the present application, since the voltage of the second pin may change due to interference with the first controller or PMIC, this may cause the first integrated circuit to directly control the first switch tube to be turned on. Therefore, in order to avoid the above situation, the user can use the above method to supply power to the mainboard with the second power supply to generate a specific sequence of pulse voltage signals (i.e., the second voltage signal), and the first integrated circuit will control the first switch tube to be turned on only when the second voltage signal meets the second condition.

It can be seen that when it is necessary to conduct the path between the battery and the mainboard, that is, when it is necessary to control the battery to continue to supply power to the mainboard, the second power supply can be controlled to supply power to the mainboard according to the third duration to generate a second voltage signal that satisfies the second condition. In this way, the first integrated circuit can conduct the path between the battery and the mainboard according to the second voltage signal that satisfies the second condition, rather than conducting the path between the battery and the mainboard according to an arbitrary signal. Therefore, it can be avoided that the path between the battery and the mainboard is conducted due to interference. In this way, it can be avoided that the battery supplies power to the mainboard due to interference.

In some embodiments of the present application, the above step 101 can be specifically implemented through the following step 101b.

Step 101b: When the path between the battery of the electronic device and the mainboard of the electronic device is connected and the voltage of the battery is less than or equal to the low voltage protection threshold, the electronic device controls the first switch group to switch between the first state and the second state through the first controller.

In this way, it can be seen that since the first controller can control the first switch group to switch between the first state and the second state when the path between the battery and the mainboard is turned on and the battery voltage is less than or equal to the low voltage protection threshold, it can trigger the first integrated circuit to control the first switch tube to disconnect, and then the path between the battery and the mainboard can be disconnected, so that the battery stops supplying power to the mainboard. Therefore, the situation where the battery has a low power for a long time can be reduced, thereby reducing the occurrence of battery bulging and the like. In this way, the safety of electronic equipment can be improved.

In some embodiments of the present application, before the above step 101b, the control method provided by the embodiment of the present application may further include the following step 301 or step 302.

Step 301: When the path between the battery and the mainboard is connected and the electronic device is in the power-on state, the electronic device adjusts the threshold value of the low voltage protection threshold from the initial threshold value to the first threshold value through the first integrated circuit.

In the embodiment of the present application, the first threshold value is smaller than the initial threshold value.

It can be understood that when the battery supplies power to the mainboard and the electronic device is in a powered-on state, the electronic device can lower the threshold value of the low voltage protection threshold through the first integrated circuit.

Step 302: When the path between the battery and the mainboard is connected and the electronic device is in a shutdown state, the electronic device adjusts the threshold value of the low voltage protection threshold from the initial threshold value to the second threshold value through the first integrated circuit.

In the embodiment of the present application, the second threshold value is greater than the initial threshold value.

It can be understood that when the path between the battery and the mainboard is connected and the electronic device is in a shutdown state, the electronic device can increase the threshold value of the low voltage protection threshold through the first integrated circuit.

Thus, it can be known that, since the first integrated circuit can lower the threshold value of the low voltage protection threshold when the path between the battery and the mainboard is conductive and the electronic device is in the power-on state, that is, the first integrated circuit can lower the threshold value of the low voltage protection threshold when the user needs to use the electronic device, it can reduce the situation that the electronic device is shut down due to the battery voltage being lower than the first threshold value during the execution of high-load tasks, thereby reducing the situation that the user cannot use the electronic device normally when the user needs to use the electronic device. Alternatively, the first integrated circuit can raise the threshold value of the low voltage protection threshold when the path between the battery and the mainboard is conductive and the electronic device is in the power-off state, that is, the first integrated circuit can raise the threshold value of the low voltage protection threshold when the user does not need to use the electronic device, thereby further reducing the power consumption of the battery, thereby reducing the situation that the battery has a low power for a long time.
