摘要： An airbag apparatus connected with a battery includes activation circuits each of which has a squib and a high-side switching element, a safing switching element connected between the battery and the activation circuits, a safing switch control circuit controlling the safing switching element to provide a target voltage to the activation circuits, a terminal voltage acquiring circuit that acquires a terminal voltage of each squib, and a target voltage setting circuit that sets the target voltage. When a maximum-terminal voltage is lower than a reference voltage, the target voltage setting circuit sets the target voltage to be equal to the reference voltage. When the maximum-terminal voltage is higher than the reference voltage, the target voltage setting circuit sets the target voltage to correspond to the maximum-terminal voltage so that a reverse current is avoided in the high-side switching element.
