Abstract

The invention relates to a driving circuit comprising a driver control circuit, a first and a second driving transistor and a current limiting device. In order to limit the current flowing through the driving transistor, said current limiting device controls the voltage at the gate of said first driving transistor. A control input of the current limiting device is used to adjust the current-limitation application point to the load to be controlled by a negative feedback. According to a second embodiment, a driving circuit having one of its two transistors designed as a MOSFET and the other one as a bipolar transistor is produced in such a way that diodes of the two driving transistors block the switched-off supply voltage or transmit the voltage according to a voltage applied on the output of said driving circuit.
