Title:
POWER DEVICE WITH INTEGRATED GATE DRIVER
Document Type and Number:
WIPO Patent Application WO/2017/190652
Kind Code:
A1
Abstract:
A self-bootstrap integrated gate driver circuit with high driving speed, enhanced driving capability and rail-to-rail output. A capacitor (120) and a diode (118) are used with a first inverter (102) coupled to a control signal input terminal, a second inverter (104) coupled to the first inverter (102), a push-pull circuit (106) comprising a pull-up transistor (116) and a pull-down transistor (115) and a power device comprising a power device transistor (108) with a gate. The control signal input at one state controls the first inverter (102) to a first output state, turns on the pull-down transistor (115) to discharge the gate of the power device transistor (108), turns off the power device and charges the capacitor (120) through the diode (118). The control signal input in another state controls the first inverter (102) to a second output state, turns off the pull-down transistor (115) and turns on the pull-up transistor (116) via the capacitor (120) to turn on the power device.
