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.
