UCC21521CDWR

Overview

The UCC21521CDWR is a dual-channel reinforced isolated gate driver manufactured by Texas Instruments. It features a 5.7kVrms isolation voltage and provides a 4A source and 6A sink peak output current. The device supports power MOSFETs, IGBTs, and SiC MOSFETs with a maximum propagation delay of 30ns. It operates within a temperature range of -40°C to +125°C and utilizes a 16-SOIC surface-mount package.

Feature Summary

Dual-channel architecture supporting universal low-side, high-side, or half-bridge configurations
Reinforced galvanic isolation with 5.7kVrms capability for robust noise immunity
Integrated enable functionality and programmable deadtime control

Applications

Driving power MOSFETs in industrial motor drives
Gate driving IGBTs for inverters and converters
Switching SiC MOSFETs in high-frequency power supplies

Procurement Notes

Verify the specific suffix 'CDWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB design guidelines. Ensure compliance with RoHS3 standards and check the Moisture Sensitivity Level (MSL 2) requirements for storage and reflow soldering profiles prior to procurement.

Selection Notes

Select this component when high-speed switching with strong isolation is required for wide-bandgap devices like SiC. The 6A sink current ensures fast turn-off times for reducing switching losses. Consider the 30ns propagation delay limit for timing-sensitive applications. The dual-channel design simplifies board space compared to single-channel alternatives.

Part Context

This part belongs to the UCC21521 series of isolated gate drivers from Texas Instruments. It is designed specifically for demanding power electronics applications requiring reliable signal transmission across isolation barriers. The device integrates capacitive coupling technology to achieve high common-mode transient immunity.
