Abstract
A control system includes a system power supply IC that operates based on a voltage outputted from a power supply circuit and supplies a voltage for operating a microcomputer to the microcomputer, monitors an abnormal condition of the microcomputer, and outputs a reset signal for resetting the microcomputer to the microcomputer when detecting an abnormal condition of the microcomputer. When detecting the abnormal condition of the microcomputer, the system power supply IC outputs a switch opening signal for forcibly turning off a switch, which, in response to the switch opening signal, stops supplying the voltage outputted from the power supply circuit to the motor driving circuit.
