Abstract

An integrated circuit having a power transistor and a circuit arrangement functioning in a temperature dependant manner and thermally coupled to the power transitor. The integrated circuit is used to reliably disconnect the power transistor in the event of overheating., particularly in the case of inductive loads, and does not reactivate the power transistor until, for example, an edge change has occurred at the base terminal of the integrated circuit.
