Summary:An electric circuit for triggering a piezoelectric element, in particular of a fuel injection system of a motor vehicle. Two transistors connected in series and triggerable using a clock pulse are provided, whose shared connecting point is coupled to the piezoelectric element and one of which is provided for discharging the piezoelectric element. In the event of an error, the transistor provided for discharging can be triggered using the clock pulse.
