A power supply control circuit for a vehicle includes: a first input terminal to which a voltage output from an DC-DC converter converting a power supply voltage is supplied; a second input terminal to which the power supply voltage is supplied; an output terminal to output a voltage for controlling semiconductor elements that generate a drive current for a motor generator and have unsaturated region characteristics; a switch circuit having one end connected to the first input terminal and the other end connected to the output terminal, the switch circuit is turned on based on a signal applied to the control terminal to establish electrical connection between the first input terminal and the output terminal, on the other hand, the switch circuit is turned off based on a signal applied to the control terminal to cuts off between the first input terminal and the output terminal; and a switch controller that controls the switch circuit by applying a signal to the control terminal based on the voltage of the second input terminal.
