Abstract
A circuit arrangement for driving a semiconductor switch includes an undervoltage detection circuit to indicate an undervoltage state when a supply voltage falls below a voltage threshold value. A temperature detection circuit indicates that a temperature of a semiconductor switch exceeds a temperature threshold value. A control circuit for driving the semiconductor switch deactivates the semiconductor switch when the undervoltage detection circuit indicates an undervoltage state, and to reactivate the semiconductor switch when the undervoltage detection circuit no longer indicates an undervoltage state. In this case, the reactivation is delayed by a defined delay time when the semiconductor switch was previously deactivated due to an undervoltage state and the temperature detection circuit indicates that the temperature of the semiconductor switch exceeds the temperature threshold value.
