3 Description

UCC27714 is a 600-V high-side, low-side gate driver

with 4-A source and 4-A 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

for operating with bootstrap supplies. The device

features excellent robustness and noise immunity

with capability to maintain operational logic at

negative voltages of up to –8 VDC on HS pin (at VDD

= 12 V).

The device accepts a wide range bias supply input

from 10 V to 20 V and offers UVLO protection for

both the VCC and HB bias supply pins. UCC27714 is

available in SOIC-14 package and rated to operate

from –40°C to 125°C.
