UCC23514MDWVR

Overview

The UCC23514MDWVR is a single-channel optically isolated gate driver manufactured by Texas Instruments. It provides high-voltage isolation for controlling IGBTs, MOSFETs, and SiC MOSFETs. The device features a peak output current of 4.5 A source and 5.3 A sink. It operates within a supply voltage range of 15 V to 30 V and supports a maximum propagation delay of 105 ns. The component is housed in an SOIC-8 package with a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Opto-compatible design enabling direct interface with standard optocoupler inputs
• High-voltage isolation capability rated at 5 kVrms for safe operation in high-power circuits
• Integrated under-voltage lockout (UVLO) protection to ensure reliable switching performance

Applications

• Industrial motor drives
• Inverter systems
• Uninterruptible power supplies (UPS)

Procurement Notes

Verify the specific suffix MDWVR corresponds to the required military-grade or extended temperature variant if applicable, as standard versions may differ. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to guarantee alignment with current design specifications.

Selection Notes

Select this component when high-speed switching with optical isolation is required for power semiconductors. The 5 kVrms isolation rating suits applications demanding significant galvanic separation between control and power stages. Consider the SOIC-8 package constraints for PCB layout. Evaluate the 4.5 A/5.3 A drive strength against the target switch's gate charge requirements to ensure adequate turn-on and turn-off speeds.

Part Context

This part belongs to the UCC23514 series of isolated gate drivers. It shares core electrical characteristics with variants like UCC23514EDWVR and UCC23514VDWVR, differing primarily in qualification standards or packaging details. The series is designed to replace traditional discrete isolation solutions, offering integrated functionality in a compact form factor for modern power electronics designs.

Replacement Considerations

UCC23514EDWVR and UCC23514VDWVR are functionally equivalent parts within the same family. Verify pin compatibility and thermal performance before substitution. No other distinct substitute part numbers are publicly confirmed for this specific model.
