Automotive 230V 4A half-bridge driver with 8V UVLO, and enable

The UCC278X4-Q1 is a 230V half-bridge gate driver with 3.5A source, 4A sink

current, targeted to drive power MOSFETs. The device consists of one

ground-referenced channel (LO) and one floating channel (HO) which is designed to

drive half-bridge configured MOSFETs operating with bootstrap power supplies. The

device features fast propagation delays and excellent delay matching between both

channels. The UCC278X4-Q1 allows a wide VDD operating

voltage of 8.5V to 20V to support a wider range of gate voltage drive, as well as

UVLO protection for both the low-side (VDD) and the high-side (HB) bias supplies.

The UCC27834-Q1 includes an interlock function option to

prevent both outputs from being turned on simultaneously

The device features robust drive with

excellent noise and transient immunity including high dV/dt tolerance (100V/ns), and

wide negative transient safe operating area (NTSOA) on the switch node (HS). The UCC278X4-Q1 is available in the SOIC-8 pin package and is

rated to operate from –40°C to 150°C.
