Abstract (en)
[origin: DE19624530A1] A circuit arrangement for an ignition stage, in particular for the ignition circuit of a motor vehicle, has a multiple Darlington transistor (Darlington) which drives a primary winding of an ignition coil, and a driving circuit for the Darlington. An npn-Darlington (T5) is provided whose collector is connected to the positive pole (14) of a voltage source and whose emitter is connected to a first connection of the primary winding (16) of the ignition coil (18), whereas the second connection of the primary winding (16) is earthed. The Darlington (T5) is driven by means of a decoupling stage which decouples the driving circuit from a negative blocking voltage applied to the Darlington base when the Darlington (T5) is switched off.
