Abstract
A control device including: an input terminal for receiving a logic control signal; an output terminal for delivering an output control signal from the high-voltage MOS transistor; a first NMOS control transistor with low internal impedance, which is connected between ground and the output terminal and the gate of which is connected to the input terminal; and a second PMOS control transistor, which is connected between a supply terminal and the output terminal and the gate of which is connected to the input terminal by a bipolar transistor mounted to a common base, and which is current controlled at the emitter thereof by a capacitive connecting circuit.
