Abstract

A semiconductor switch, particularly an MOS high-side power switch, having at least one power transistor for driving a load, and having a circuit for driving the power transistor via an external control signal by activating the power transistor over its gate. In order to also assure low dissipated power of the MOS power transistor given a reversal of the power supply, an auxiliary circuit is provided for the activation of the MOS power transistor via its gate given upon such reversal.
