The UCC27735-Q1 is a 700V half-bridge gate driver with 3.5A source and 4A sink current capability, targeted to drive power MOSFETs or IGBTs. The device comprises of one ground-referenced channel (LO) and one floating channel (HO) which is designed to drive half-bridge configured MOSFET's and IGBT's operating with boostrap supplies. The device features robust drive with excellent noise and transient immunity including large negative voltage tolerance on its inputs, high dV/dt tolerance, and wide negative transient safe operating area (NTSOA) on the switch node (HS).

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 UCC27735-Q1 is available in an SOIC package and is rated to operate from –40°C to 150°C.
