Abstract: A protection circuit for a control terminal of a power device of the type comprising at least one resistive element connected between at least one output terminal of a driver and the control terminal of the power device includes at least one turning-off transistor having its conduction terminals connected to the control terminal of the power device and to at least one output terminal of the driver, respectively. A control terminal is coupled to the control terminal of the power device through a second resistive element.
