Abstract
A drive circuit for an AC ignition circuit, which has at least one capacitor and at least one trigger element, which is used to deploy a restraint system in a motor vehicle, has a bridge circuit with four electronically controllable switches, of which two switches are connected in series between a supply voltage and ground, and the ignition circuit forms a bridge shunt between both pairs of switches connected in parallel. If a fault occurs in the bridge circuit, the individual switches are triggered so that charging and discharging of the capacitor in the ignition circuit is guaranteed in spite of the fault.
