  • DUAL INTEGRATED GATE-DRIVER WITH REVERSE CURRENT FAULT PROTECTION FOR USB TYPE-C AND USB POWER DELIVERY
    Publication number: 20210263878
    Abstract: A dual-integrated gate-driver with reverse current protection (RCP) fault protection is described. A Universal Serial Bus Type-C (USB-C) controller includes a first terminal, a second terminal, and a dual-gate driver. The dual-gate driver drives a first power field effect transistor (FET) coupled to the first terminal and a second power FET coupled to the second terminal. The first power FET and the second power FET are connected in series between a voltage bus (VBUS_C) terminal of a USB Type-C connector and a voltage supply to deliver power to the VBUS_C terminal. A breakdown voltage of each of the first power FET and the second power FET is less than 20 volts. The dual-gate driver controls the first power FET and the second power FET in response to at least one of a short circuit event or a reverse current event.
