3 Description

The UCC21530-Q1 is an isolated dual-channel gate

driver with 4A source and 6A sink peak current. It

is designed to drive IGBTs, Si MOSFETs, and SiC

MOSFETs up to 5MHz.

The input side is isolated from the two output

drivers by a 5.7kVRMS reinforced isolation barrier,

with a minimum of 125V/ns common-mode transient

immunity (CMTI). Internal functional isolation between

the two secondary-side drivers allows a working

voltage of up to 1850V.

This device can be configured as two low-side drivers,

two high-side drivers, or a half-bridge driver with

programmable dead time (DT). The EN pin pulled low

shuts down both outputs simultaneously and allows

for normal operation when left open or pulled high. As

a fail-safe measure, primary-side logic failures force

both outputs low.

The device accepts VDD supply voltages up to 25V.

A wide input VCCI range from 3V to 18V makes the

driver suitable for interfacing with both analog and

digital controllers. All the supply voltage pins have

under voltage lock-out (UVLO) protection.
