DEVICE FOR CONTROLLING A HIGH-VOLTAGE TRANSISTOR, IN PARTICULAR A MOS TRANSISTOR OF A HIGH-VOLTAGE RADIO-FREQUENCY GENERATOR FOR THE SPARK IGNITION OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a control device comprising: an input terminal (IN) for receiving a logic control signal; an output terminal (OUT) for delivering an output control signal from the high-voltage MOS transistor; a first NMOS control transistor (Q6) with low internal impedance, which is connected between the earth and the output terminal and the gate of which is connected to the input terminal; and a second PMOS control transistor (Q5) which is connected between a supply terminal and the output terminal and the gate of which is connected to the input terminal by means of a bipolar transistor (Q2) which is mounted to a common base and which is current controlled at the emitter thereof by means of a capacitive connecting circuit (C2, R2, Q1).
