Abstract: The driving circuit comprises a detection resistance (R1) interposed between the emitter of the power transistor (T1) and ground, a first circuit part (G1, T4, T5, R2) suitable for generating a first current (I2) being a function of the voltage across said detection resistance (R1) and a second circuit part (TD2, T3, TD1, T2) suitable for generating a driving base current (Ib) of the power transistor (T1) that is proportional to said first current (I2).

Abstract: In a switching circuit suitable for connecting a first circuit node (1) to a second (2) or to a third (3) circuit node in relation to the latter's potential, particularly for controlling the potential of an insulation region of an integrated circuit in relation to the substrate's potential, there is a first NPN bipolar transistor (T1) with the function of a switch having the collector connected to the first circuit node (1) and the emitter connected to the second circuit node (2) and a second NPN bipolar transistor (T2) with the function of a switch having the collector connected to the first circuit node (1) and the emitter connected to the third circuit node (3). There are means (D1, T5, T6) for maintaining the base of the second transistor (T2) at a constant pre-set bias voltage.
