Overview
The UCC21530QDWKRQ1 is an isolated dual-channel gate driver developed by Texas Instruments. This device is designed to drive IGBTs, Si MOSFETs, and SiC MOSFETs up to 5 MHz, making it suitable for high-frequency applications. It features a 5.7 kVRMS reinforced isolation barrier between the input and output drivers, ensuring high common-mode transient immunity (CMTI) of greater than 125 V/ns. The gate driver is configured to operate as two low-side drivers, two high-side drivers, or a half-bridge driver with programmable dead time (DT).
