摘要： A fourth constant-voltage power circuit directly powered from an on-vehicle battery is connected, in parallel through a serial resistor, to a second constant-voltage power circuit powered from the on-vehicle battery through an output contact of a power relay, and is connected to a drive power terminal of a microprocessor. When the output contact is closed, the microprocessor operates with an output voltage of the second constant-voltage power circuit, and an output current of the fourth constant-voltage power circuit is limited to less than or equal to a predetermined value by the serial resistor. During the operation stop at which a power switch is open, a micro standby current is supplied from the fourth constant-voltage power circuit to the microprocessor.
