A power supply monitoring circuit monitors an in-vehicle power supply in an ECU. The ECU has power supply circuits powered by the in-vehicle power supply through a power supply line and supplying power to a downstream load. The power supply monitoring circuit includes a voltage supply monitoring circuit and a control circuit. The power supply line is commonly connected to the in-vehicle power supply and the power supply circuits by having a branching node where the power supply line is branched out from the in-vehicle power supply to the power supply circuits. The voltage monitoring circuit monitors the in-vehicle power supply by monitoring the power supply line. The control circuit controls the power supply circuits or a device powered by the power supply circuits to discharge operational charges remained in the power supply circuits or the device.
