Abstract
An electronic circuit has an output driver (DRV) for providing a driving signal (U). The output driver has a transistor (T) with a first main terminal, a second main terminal and a control terminal coupled to receive a control signal (V), a power supply terminal (V), an output terminal (OUT) for providing the driving signal (U) that is coupled to the second main terminal, and a sensing resistor (R) coupled between the power supply terminal (V) and the first main terminal. The output driver (DRV) further has means for temporarily disabling the coupling between the control terminal and the control signal (V) during a peak voltage across the sensing resistor (R). The means may have a circuit that has a unidirectional current behavior, such as a diode (D), in series with the control terminal of the transistor (T).
