Overview
The UCC21530DWKR is an isolated dual-channel gate driver produced by Texas Instruments. This device is designed to drive IGBTs, Si MOSFETs, and SiC MOSFETs up to 5MHz. It features a 4A source and 6A sink peak current, making it suitable for a variety of high-power applications. The gate driver is isolated from the input side by a 5.7kVRMS reinforced isolation barrier, ensuring high common-mode transient immunity (CMTI) of greater than 125V/ns. The device can be configured as two low-side drivers, two high-side drivers, or a half-bridge driver with programmable dead time (DT).
