Abstract: A steering control device capable of suitably handling a temporary drop in a supply voltage of a vehicle is provided. An ECU includes a microcomputer, a pre-driver, and an inverter. The microcomputer generates a command signal for the pre-driver. Upon being initialized by the microcomputer, the pre-driver becomes operable to generate a drive signal for the inverter based on the command signal. The inverter converts direct current power supplied from a battery into alternating current power for a motor by operating based on the drive signal. When a drop in a voltage of the battery is detected, the pre-driver transmits an abnormal-condition detection signal to the microcomputer and stops operating by resetting a state of the pre-driver to an initial state where the pre-driver is not initialized yet. When the abnormal-condition detection signal is received, the microcomputer re-initializes the pre-driver.
