The UCC278X4 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 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 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 is available in the SOIC-8 pin package and is rated to operate from –40°C to 150°C.
