Overview
The Texas Instruments UCC20520DWR is an isolated single-input, dual-channel gate driver designed to drive power MOSFETs, IGBTs, and SiC MOSFETs. It features 4-A source and 6-A sink peak current, making it suitable for high-frequency applications up to 5 MHz. The device boasts best-in-class propagation delay and pulse-width distortion, ensuring high efficiency and power density. The input side is isolated from the two output drivers by a 5.7-kVRMS reinforced isolation barrier, providing a minimum of 100-V/ns common-mode transient immunity (CMTI).
