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.
