ABSTRACT:
A device for controlling a voltage-controlled switch, including two circuits respectively for setting to the high level and for setting to the low level a control terminal of the voltage-controlled switch, one at least of the circuits including a power transistor capable of connecting the control terminal to a high, respectively low voltage, a bipolar control transistor having its emitter, respectively its collector, connected to the control terminal of the power transistor, the base of the control transistor being likely to receive a control current and a first diode connected between a first predetermined voltage smaller than the high voltage, and the base of the control transistor.
