UCC23511DWY

Overview

The UCC23511DWY is a single-channel opto-compatible reinforced isolated gate driver manufactured by Texas Instruments. It provides 5.7-kVRMS isolation and delivers a 1.5-A source and 2-A sink peak output current, suitable for driving IGBTs, MOSFETs, and SiC MOSFETs. The device operates within a temperature range of -40°C to +125°C and features a maximum propagation delay of 105 ns, with rise and fall times of 28 ns and 25 ns respectively. It is housed in a SOIC-6 package.

Feature Summary

• Opto-compatible input design allows pin-to-pin drop-in replacement for traditional optocoupler-based gate drivers.
• Reinforced insulation capability ensures safety compliance for high-voltage applications.

Applications

• Driving IGBT modules in industrial motor drives
• Gate control for power MOSFETs in inverters
• Switching control for Silicon Carbide (SiC) MOSFETs

Procurement Notes

Verify the specific suffix DWY to confirm the SOIC-6 tube packaging variant. Confirm end-of-life status as discontinuance notifications have been issued for this component family. Ensure compatibility with existing PCB footprints designed for standard SOIC-6 packages before procurement.

Selection Notes

Select this component when replacing legacy optocoupler gate drivers without redesigning the board layout. Consider the 1.5A/2A current drive capability against load requirements. Verify that the 5.7kVRMS isolation rating meets the system's creepage and clearance requirements.

Part Context

This part belongs to the UCC2351x series of isolated gate drivers from Texas Instruments. It shares functional similarities with other members like the UCC23511BDWY but differs in specific manufacturing revisions or packaging configurations. The series targets high-reliability power conversion systems requiring robust galvanic isolation.

Replacement Considerations

Check for direct substitutes such as the UCC23511BDWY, noting potential differences in revision levels or availability status due to end-of-life notices.
