UCC23514VDWVR

Overview

The UCC23514VDWVR is a single-channel optically compatible isolated gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 15 V to 30 V and delivers an output current of 5 A. The device features a maximum propagation delay of 105 ns, with rise and fall times of 28 ns and 25 ns, respectively. It provides 5 kVrms isolation and functions in temperatures from -40°C to +125°C. Packaged in an SOIC-8 (DWV) format, it supports high-side and low-side configurations.

Feature Summary

• Integrates Miller clamp functionality to prevent false turn-on events during high dv/dt switching conditions.
• Features split output pins to allow independent control of peak source and sink currents for optimized switching performance.
• Provides optical compatibility with standard optocouplers, facilitating direct replacement in existing designs.

Applications

• Industrial motor drives
• Inverter systems
• Switched-mode power supplies

Procurement Notes

Verify the specific suffix DWVR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for moisture sensitivity levels as indicated in the datasheet. Validate that the SOIC-8 footprint matches the target PCB layout requirements.

Selection Notes

Select this component for applications requiring robust isolation with optocoupler pin-out compatibility. The integrated Miller clamp simplifies design complexity compared to discrete solutions. Consider the split-output capability if asymmetric drive strength is required for specific power devices.

Part Context

This part belongs to the UCC23514 series of isolated gate drivers. It shares core specifications with variants like UCC23514EDWVR but differs in package or thermal characteristics. The series targets high-reliability industrial applications requiring galvanic isolation between control and power stages.

Replacement Considerations

UCC23514EDWVR is a documented alternative within the same family offering similar electrical performance.
