Abstract
An electronic device includes: a plurality of loads, a switching element provided in a current path connected to the plurality of loads, a failure diagnosis unit that performs failure diagnosis according to voltages applied to the plurality of loads, and a driving circuit that drives the switching element. The driving circuit outputs, to the switching element, a driving control signal that represents a result of comparison between a load signal resulting from converting a current flowing in the current path to a voltage and a reference signal used as a reference for the operation of the switching element. If the failure diagnosis unit detects a voltage outside a normal voltage range, the failure diagnosis unit decides that the load is in an abnormal state.
