Abstract: The invention concerns a driver circuit for driving a P-Channel MOSFET. The driver circuit is fed by a DC voltage supplied at a power input and it receives a control signal at a control input. The control signal includes the information for controlling a switching of a P-Channel MOSFET the gate of which is connected to a drive output of the driver circuit. For generating the drive signal the driver circuit includes a turn-off bipolar transistor which is powered by the supply voltage received at the power input in that its collector is connected to the power input. The control signal received at the control input is amplified by means of a current amplifier and fed to the base of the bipolar transistor via an inverting capacitor. In response to the amplified control signal at its base, the bipolar transistor actively generates a turn-off signal and provides the turn-off signal to the drive output in that the emitter of the bipolar transistor is connected to the drive output.
