UCC23511DWYR

Overview

The UCC23511DWYR is a single-channel, opto-compatible isolated gate driver featuring 5.7-kVRMS reinforced isolation. It delivers a 1.5-A source and 2-A sink peak output current, supporting IGBTs, MOSFETs, and SiC MOSFETs. The device operates within an extended temperature range of -40°C to +125°C and utilizes a SOIC-6 (DWY) package. Key electrical parameters include a maximum propagation delay of 105 ns, a rise time of 28 ns, and a fall time of 25 ns. Power dissipation is rated at 750 mW.

Feature Summary

• Provides pin-to-pin compatibility with optocoupler-based isolated gate drivers for direct drop-in upgrades.
• Features opto-compatible input architecture to simplify interface design with standard control logic.

Applications

• Driving IGBT modules in industrial motor drives
• Switching power MOSFETs in high-frequency converters
• Controlling SiC MOSFETs in advanced power electronics

Procurement Notes

Verify the specific suffix 'DWYR' confirms the tape-and-reel packaging format rather than tube packaging. Confirm the component status as obsolete or end-of-life through official Texas Instruments channels before finalizing procurement plans. Ensure the revision level matches the required datasheet version for accurate timing specifications.

Selection Notes

Select this component when replacing existing optocoupler gate drivers without redesigning the PCB footprint. Choose the UCC23511DWYR for applications requiring moderate peak drive currents up to 2 A. Consider the SOIC-6 package constraints for thermal management and isolation creepage distances in dense layouts.

Part Context

This part belongs to the UCC2351x family of single-channel isolated gate drivers from Texas Instruments. It shares the same physical package and pinout as other variants in the series but offers specific drive strength characteristics optimized for general-purpose switching applications.

Replacement Considerations

Official substitutes include UCC23511DWY (tube package) for identical functionality with different packaging. Verify availability of alternative single-channel drivers if the UCC23511DWYR is discontinued.

FAQ

Does the UCC23511DWYR support SiC MOSFET switching?

Yes, the datasheet explicitly lists SiC MOSFETs among the supported load types alongside IGBTs and standard MOSFETs.

What is the isolation rating of the UCC23511DWYR?

The device provides 5.7-kVRMS of reinforced isolation between the input and output channels.
