Patent ID: 7362157

Claim:
A circuit arrangement comprising: a circuit input; a circuit output; a first transistor including a load path and a control terminal, wherein the load path is connected between the circuit input and the circuit output; a path connected between the control terminal of the first transistor and the circuit input; a first driver circuit connected to the control terminal of the first transistor, wherein the first driver circuit is designed to control a current flow through the first transistor; a second driver circuit configured to detect a voltage difference between the circuit input and the circuit output, wherein the second driver circuit is further configured to drive the first transistor in a blocking action as a function of the voltage difference, the second driver circuit including a comparator having a first comparator input connected to the circuit output, and a second input connected to the circuit input; and a controllable switching element connected between the control terminal of the first transistor and the first load terminal of the first transistor, wherein the controllable switching element is driven by the comparator.
