Abstract

A circuit arrangement and a method for actuating a power semiconductor switch wherein said power semiconductor switch has a load current input, a load current output and a control input, having a first voltage detection device, which is able to be switched on and off, for detecting a first voltage present between the load current input and the load current output, a second voltage detection device, which is able to be switched on and off, for detecting a second voltage present between the control input and the load current output, and having a regulating device that is designed to cyclically assess a second voltage value of the second voltage and, if a second threshold value of the second voltage value is reached, to switch on the first voltage detection device, in particular if no further fault signal is present.
