UCC21530-Q1 - Automotive, 4-A, 6-A, 5.7-kVrms isolated dual-channel gate driver with enable

The UCC21530-Q1 is an isolated dual-channel gate driverwith 4-A source and 6-A sink peak current. It is designed to drive IGBTs and SiC MOSFETs up to5-MHz with best-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a5.7-kV_RMS reinforced isolation barrier, with a minimum of 100-V/nscommon-mode transient immunity (CMTI). Internal functional isolation between the two secondary-sidedrivers allows a working voltage of up to 1850 V_MAX.

This driver can be configured as two low-side drivers, two high-side drivers, or ahalf-bridge driver with programmable dead time (DT). The EN pin pulled low shuts down both outputssimultaneously and allows for normal operation when left open or pulled high. As a fail-safemeasure, primary-side logic failures force both outputs low.

The device accepts VDD supply voltages up to 25 V. A wide input VCCI range from 3 V to 18V makes the driver suitable for interfacing with both analog and digital controllers. All thesupply voltage pins have under voltage lock-out (UVLO) protection.

With all these advanced features, the UCC21530-Q1 enableshigh efficiency, high power density, and robustness in a wide variety of power applications.
