The UCC21530 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.
