Abstract
A drive circuit for a firing element of an occupant protection system comprises first and second supply potential terminals and first and second firing element terminals. A first semiconductor switching element is integrated in a first semiconductor body and has a first load terminal coupled to the first supply potential terminal and a second load terminal coupled to the first firing element terminal. A second semiconductor switching element is integrated in a second semiconductor body and has a first load terminal coupled to the second firing element terminal and a second load terminal coupled to the second supply potential terminal. The first and second semiconductor bodies are applied to a thermally conductive carrier element and commonly housed. A temperature detector is integrated in the second semiconductor body and provides an overtemperature signal at an output of the drive circuit upon detection of an overtemperature of the first semiconductor switching element.
