UCC23514EDWVR

Overview

The UCC23514EDWVR is a single-channel optically isolated gate driver from Texas Instruments, housed in an SOIC-8 surface-mount package. It provides high-voltage isolation with a maximum rating of 5kVrms. The device features a peak output current capability of 4A source and 5A sink. Electrical specifications include a maximum propagation delay of 105 ns, a rise time of 28 ns, and a fall time of 25 ns. It operates within a supply voltage range of 15 V to 30 V and supports both high-side and low-side configurations. The component functions reliably across an extended temperature range from -40°C to +125°C.

• Provides galvanic isolation for safe signal transmission between control and power stages
• Delivers robust drive strength suitable for switching wide-bandgap semiconductors
• Ensures fast switching performance through optimized rise and fall times

Applications

• Gate driving for silicon carbide (SiC) MOSFETs
• Gate driving for gallium nitride (GaN) HEMTs
• Industrial motor drive systems
• High-frequency DC-DC converters

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required package variant and tape-and-reel specifications. Cross-reference manufacturer datasheets to validate technical parameters before integration into design files.

Selection Notes

Select this component when high-speed optical isolation is required for single-channel applications. Ensure the input logic levels are compatible with the driver interface. Verify that the thermal management solution supports the operating temperature range. Confirm that the isolation voltage rating meets the system safety requirements.

Part Context

This device belongs to the UCC23514 series of optically isolated gate drivers. The series is designed to replace traditional transformer-based or capacitive coupling solutions in modern power electronics. It integrates an LED driver and a photodetector to provide reliable signal transfer across the isolation barrier.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family. Verify functional equivalence regarding isolation ratings and drive currents. Review updated datasheets for any changes in recommended operating conditions.
