Abstract

PURPOSE: To avoid the malfunction of control unit due to power supply application and interruption, by supplying the signal voltage to the termination load of signal line between the driver circuit and receiver circuit via the diode from each power supply of the said circuits.
CONSTITUTION: When the power supply 4 of the control unit 1 is OFF, voltage is fed to the signal line 3 via the diode 11 and resistor 7 from the power supply 5 of the control unit 2, and the signal line 3 in kept to stable voltage level. When the power supply 5 of the control unit 2 is OFF and the power supply 4 of the control unit 1 is ON, it can be explained in the similar way by using the diode 10 and resistor 7. Further, if the voltage value of the power supplies 4 and 5 is different, the current flow between the power supplies is cut with the diodes 10, 11. Assuming that the voltage V1 of the power supply 4 and V2 of the power supply 5 are V1>V2, the current from the power supply 4 is cut off with the diode 11 and does not flow to the power supply 5.
