Abstract

A circuit configuration for driving an ignition coil includes a first semiconductor switch having a load path connected in series with a primary winding of the ignition coil, and having a control electrode, which is driven in accordance with a first drive signal. The circuit configuration further includes a second semiconductor switch having a load path connected in parallel with the primary winding and having a control electrode, which is driven in accordance with a second drive signal.
