Claim:
1. A drive circuit for driving a control electrode of a semiconductor switch, comprising the following: a first output node for connection to the control electrode of the semiconductor switch; a voltage supply circuit, a first switching stage connected to the voltage supply and a second switching stage connected to the voltage supply; a first resistor network, which is connected between the first switching stage and the first output node; a second resistor network, which is connected between the second switching stage and the first output node; a first reference node for connection to a load electrode of the semiconductor switch, and a control logic, which is designed to generate control signals for the guiding of the first switching stage and the second switching stage in such a way that in a first operating mode of the semiconductor switch the semiconductor switch is driven only via the first resistor network, and in a second operating mode of the semiconductor switch the semiconductor switch is driven only via the second resistor network or both resistor networks.
