Abstract

To obtain a highly reliable electronic control device capable of reliably causing a microcomputer to perform normal termination and normal re-activation by controlling a power supply voltage. According to the present invention, an electronic control deviceincludes a microcomputer, a power supply control unitthat controls a power supply voltage of the microcomputer, and a capacitorprovided between the power supply control unit and the microcomputer. The power supply control unitincludes a power supply unitthat supplies a first power supply voltage Vto the microcomputer by turning ON an activation signal for activating the microcomputer, and stops the supply of the power supply voltage by turning the activation signal OFF, a reset control unitthat generates a Low reset signal by turning the activation signal OFF, and a discharge control unitthat discharges electric charges of the capacitor when acquiring the Low reset signal.
