TIUCC21520ADWR

Overview

The UCC21520ADWR is an isolated dual-channel gate driver designed to drive MOSFETs, IGBTs, and SiC MOSFETs with a 5700Vrms isolation rating. It features a high peak source/sink current of 4A/6A and offers a wide output supply range from 6.5V to 25V, making it suitable for high-frequency switching applications. This device utilizes capacitive coupling technology to ensure high CMTI and low propagation delay for precision power conversion.

Why Choose This Part

The component offers industry-leading propagation delay of less than 19ns and excellent channel-to-channel matching, which minimizes dead-time requirements. Its 5700Vrms isolation and high common-mode transient immunity (CMTI) of up to 100V/ns ensure robust operation in noisy high-voltage environments. The wide input voltage range of 3V to 18V allows for direct interfacing with both digital controllers and analog PWM circuits.

Applications

Getting Started

To evaluate this driver, engineers typically use the UCC21520EVM-286 evaluation module which provides a hardware platform for testing switching performance. Ensure that decoupling capacitors are placed as close as possible to the VDD and VCCI pins to minimize noise. When designing the PCB layout, maintain proper creepage and clearance distances as required by the 16-SOIC wide-body package to satisfy safety isolation standards.
