UCC21750DWR

Overview

The UCC21750DWR is a single-channel isolated gate driver from Texas Instruments, housed in a 16-pin SOIC package. It provides galvanic isolation with a rating of 5.7kVrms and supports output currents of ±10A. The device operates within a supply voltage range of 3V to 33V and functions across temperatures from -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 130ns, rise time of 33ns, and fall time of 27ns. Power dissipation is rated at 985mW.

Feature Summary

• Integrates desaturation detection for IGBT protection
• Includes internal Miller clamp to prevent false turn-on
• Supports both inverting and non-inverting logic configurations

Applications

• IGBT gate drive circuits
• SiC MOSFET switching applications
• Industrial motor drives

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure moisture sensitivity handling protocols are followed during assembly. Cross-reference the exact part number against current manufacturer listings to confirm active production status.

Selection Notes

Select this component for high-voltage isolation requirements up to 5.7kVrms. It is suitable for driving IGBTs and SiC FETs where fast switching speeds are critical. The integrated protection features reduce external component count compared to standard drivers.

Part Context

This part belongs to the UCC21750 series of isolated gate drivers. It shares core specifications with variants like the UCC21750DW but differs in packaging format. The DWR suffix specifically denotes the tape-and-reel configuration for automated surface-mount assembly.

Replacement Considerations

UCC21750DW is a tube-packaged equivalent with identical electrical characteristics.
