3 Description

The UCC2773x-Q1 is a 700V half-bridge gate driver

with 3.5A source and 4A sink current capability,

targeted to drive power MOSFETs and IGBTs. The

device comprises of one ground-referenced channel

(LO) and one floating channel (HO) which is designed

to drive half-bridge configured MOSFETs and IGBTs

operating with bootstrap supplies. The device features

robust drive with excellent noise and transient

immunity including large negative voltage tolerance

on its inputs, high dV/dt tolerance, wide negative

transient safe operating area (NTSOA) on the switch

node (HS), and interlock.

The device accepts a wide range of bias supply input

from 10V to 21V and offers UVLO protection for both

the VDD and HB bias supply pins. The UCC2773x-

Q1 is available in various packages and is rated to

operate from –40°C to 150°C.
