Abstract

Circuit arrangement for controlling an ignition coil, which has the following features:
  • a first semiconductor switch (T1) with a load path (DS), which is connected in series with a primary winding (L1) of the ignition coil, and with a control electrode (G) for the control in accordance with a first control signal (A1);
  • a second semiconductor switch (T2) with a load path (DS), which is connected in parallel to the primary winding (L1), and with a control electrode (G) for the control in accordance with a second control signal (A2).
