3 Description

The UCC27712 is a 620-V high-side and low-side

gate driver with 1.8-A source, 2.8-A sink current,

targeted to drive power MOSFETs or IGBTs.

The recommended VDD operating voltage is 10-V to

20-V for IGBT's and 10-V to 17-V for power

MOSFETs.

The UCC27712 includes protection features where

the outputs are held low when the inputs are left open

or when the minimum input pulse width specification

is not met. Interlock and deadtime functions prevent

both outputs from being turned on simultaneously. In

addition, the device accepts a wide range bias supply

range from 10 V to 22 V, and offers UVLO protection

for both the VDD and HB bias supply.

Developed with TI's state of the art high-voltage

device technology, the device features robust drive

with excellent noise and transient immunity including

large negative voltage tolerance on its inputs, high

dV/dt

tolerance,

wide

negative

transient

safe

operating area (NTSOA) on the switch node (HS),

and interlock.

The

device

consists

of

one

ground-referenced

channel (LO) and one floating channel (HO) which is

designed for operating with bootstrap or isolated

power supplies. The device features fast propagation

delays and excellent delay matching between both

channels. On the UCC27712, each channel is

controlled by its respective input pins, HI and LI.
