Example 1
In this embodiment, the power adapter of the present invention can be used as a power supply, preferably, the power outlet can be a USB TYPE C connector, and the corresponding relationship between each pin of the connector and the power adapter circuit is as follows:
TABLE 1
The plug can be understood as a power outlet of the power adapter to the device to be charged, namely a TYPE C female plug, and the plug is a power inlet on the device to be charged, namely a TYPE C male plug; the numbers a1 to a12 and B1 to B12 above are that when the device to be charged is connected to the power adapter, a1 on the socket is connected to a1 on the plug, and the other pins are correspondingly connected, for example, B9 on the drawer is connected to B9 on the tap.
Alternatively, the power outlet of the receptacle and the power inlet of the device to be charged (i.e., USB TYPE C connector) may be connected in a positive or negative manner, so that a1 on the drawer seat is connected to B1 on the tap, and the other pins are correspondingly connected, for example, B6 on the drawer seat is connected to a6 on the tap.
The GND1 and the GND2 are ground lines; VBUS1 and VBUS2 are main charging power sources; TC1, TC2, TC3, and TC4 are wireless charging signals; AC1, AC2, AC3, and AC4 are wireless charging signals of the device to be charged; DP1, DP2, DN1 and DN2 are USB receiving and outputting communication signals, and are also used for initial communication setting of charging; MODE0, MODE1, MODE, and MODE are wireless charging MODE determination signals; VCON is a power supply signal during charging and quick charging; CC1, CC2, and CC are fast charge request reply signals.
