A current/voltage converter senses a collector current flowing in the power bipolar transistor and controls conduction of a first transistor responsive thereto, the conduction of the first transistor controlling the conduction of a second transistor so as to vary the control terminal voltage in proportion to the sensed collector current of the power bipolar transistor.
