An integrated circuit (10) for driving an ignition coil (14) has a first transistor (30) providing a coil current (I.sub.COIL) at a first lead (22) of the integrated circuit. A second transistor (32) has a collector coupled to the first lead and an emitter coupled to a gate electrode of the first transistor. A gate electrode of the second transistor is coupled to a second lead (23) of the integrated circuit for receiving a control signal (V.sub.ENABLE).
