Abstract
An ignition device for an internal combustion engine comprises a preselector stage and an output stage for controlling the flow of current through the primary winding of an ignition transformer. The ignition device is particularly suited for an externally ignited internal combustion engine. The output stage comprises a pnp-transistor having its collector terminal directly coupled to a ground connection of the ignition device to improve proper loss dissipation. A decoupling device is coupled between the preselector stage and the output stage, and is provided to protect the preselector stage by decoupling it from the output stage.
