Abstract
The present disclosure relates to an USB PD-type interface including a first node receiving a first potential, a second node delivering a second potential, and a third node at a reference potential; a resistor connected between a fourth node coupled to the first node, and a fifth node; a MOS transistor connected between the fifth node and the second node; a bipolar transistor having a collector connected to a gate of the MOS transistor and an emitter connected to the fourth node or to the fifth node; and a circuit configured to deliver a control potential to a base of the bipolar transistor determined from a current in the first resistor.
