Abstract:
1. A circuit arrangement for actuating a semiconductor switch connected in series with an inductive load, the circuit arrangement comprising: a first input terminal for supplying an input signal; a second input terminal for supplying a voltage measurement signal; an output terminal for providing an actuation signal to the semiconductor switch; a control signal generation circuit configured to receive the first input signal and to sense a value of the voltage measurement signal based on the first input signal in order to provide a sample value, wherein the control signal generation circuit generates a control signal on the basis of a comparison that involves the sample value and the voltage measurement signal; and a driver circuit connected between the first input terminal and the output terminal, wherein the driver circuit generates the actuation signal based on the control signal for a given level of the input signal, wherein the actuation signal has a signal profile.
