A load driving device includes a synchronous rectifier circuit having a driving-side switching element and a reflux-side switching element; a driver control circuit controls the synchronous rectifier circuit; and a voltage monitor circuit that monitors whether the voltage of an output terminal of the synchronous rectifier circuit is within a predetermined voltage range; where the driver control circuit, upon receiving a diagnosis command, performs control so that when the driving-side switching element is switched from ON to OFF, the reflux-Side switching element is also switched to OFF; and the voltage monitor circuit detects a normal state when the voltage to be monitored is within a normal level during a period in which both the driving-side switching element and the reflux-side switching element are turned OFF.
