UCC23313DWY

Overview

The UCC23313DWY is a single-channel opto-compatible isolated gate driver manufactured by Texas Instruments. It provides high-voltage isolation of 3.75kVrms and delivers peak output currents of 4A source and 5A sink. The device operates within a supply voltage range of 15V to 30V, supporting output voltages from 14V to 33V. Key electrical characteristics include a maximum propagation delay of 105ns, a rise time of 28ns, and a fall time of 25ns. Designed for robust performance, it functions across an extended temperature range from -40°C to +125°C with a power dissipation rating of 750mW.

Feature Summary

• Opto-compatible interface simplifies integration with existing optical isolation designs
• High-voltage galvanic isolation ensures safety in high-side and low-side applications
• Fast switching speeds support high-frequency operation in power electronics

Applications

• Silicon carbide (SiC) and gallium nitride (GaN) power transistor driving
• Industrial motor control systems requiring isolated gate drive
• Inverter and converter topologies utilizing high-side switching

Procurement Notes

Verify the specific suffix 'DWY' corresponds to the SOIC-6 package variant when ordering. Confirm that the required isolation voltage and current ratings align with the target application's safety standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Selection Notes

Select this component when an opto-compatible interface is preferred over capacitive coupling for cost or legacy design reasons. It is suitable for applications requiring moderate switching speeds up to 105ns propagation delay. Consider the SOIC-6 package constraints for thermal management and PCB layout space. Evaluate the 3.75kVrms isolation barrier against system creepage and clearance requirements.

Part Context

This part belongs to the UCC2331x family of basic isolated gate drivers from Texas Instruments. It serves as a direct replacement for traditional optocoupler-based gate drive solutions while offering improved performance metrics. The DWY suffix indicates a specific tape-and-reel packaging format within the SOIC-6 footprint, distinguishing it from other pinout or package variations in the series.

Replacement Considerations

The UCC23313DWY is functionally similar to the UCC23313DWYR. Verify if the 'R' suffix denotes a specific reel quantity or manufacturing lot variation rather than a functional difference. No alternative part numbers are explicitly confirmed as direct substitutes in the provided documentation.
