Abstract: The invention relates to a driver circuit for P-channel MOS switches, of the type comprising: a power transistor (2) having a control terminal (G) and having first (D) and second (S) conduction terminals; a controlled current generator (ION) connected to said control terminal (G) for turning on the power transistor (2); a control circuit (5) for controlling the turning on of said current generator (ION); and a protection circuit (3) coupled to said control terminal (G). The driver circuit (1) further comprises a second current generator (IOFF) connected to the control terminal (G) of the power transistor (2) and in turn driven by the control circuit (5) to control the transistor turn-off. Advantageously, the control circuit (5) also receives a control signal (STOP) from the protection circuit (3) at the end of the latter's action.
