Driver device for transistors, and corresponding integrated circuit

摘要

A driver device is for switching on and off a transistor for supplying a load by driving a control electrode of the transistor. The driver device includes a first terminal connected to the control electrode of the transistor, a second terminal connected between the transistor and the load, and a current-discharge path coupled to the first terminal. The current-discharge path includes a diode and is activated when the transistor is switched off. The diode becomes non-conductive to interrupt the current-discharge path when the voltage on the second terminal reaches a threshold value.

1. A driver device for switching on and off a transistor feeding a load by driving a control electrode of the transistor, the driver device comprising:
a first terminal coupled to the control electrode of the transistor; a second terminal coupled between the transistor and the load; and a current discharge path coupled to said first terminal and being activated when the transistor is switched off, said current discharge path comprising a diode to interrupt said current discharge path based on said second terminal having a voltage reaching a threshold; with the transistor comprising a field effect transistor (FET) having a drain, and with said second terminal coupled to the drain of the FET, and with said current discharge path extending between said first and second terminals.
