Abstract
A monolithically integrated output stage includes an arrangement for detecting the load current through a power switching transistor and/or an arrangement for detecting the output voltage at a power switching transistor and/or an arrangement for detecting the chip temperature. A switching logic of the monolithically integrated output stage includes at least one output transistor for switching the output transistor on reaching at least one predetermined load current threshold and/or output voltage threshold and/or temperature threshold, where the output transistor supplies a high signal at at least one logic output. The emitter of the output transistor is coupled to the logic output, and a switching device is provided to block the output transistor at a negative collector voltage of the power switching transistor.
