UCC5310MCDWV

Overview

The UCC5310MCDWV is a single-channel isolated gate driver from Texas Instruments featuring capacitive coupling technology. It provides galvanic isolation with a 3kVrms basic and 5kVrms reinforced insulation rating. The device delivers a peak output current of 2A for sourcing and 1A for sinking, supporting high-speed switching applications. It operates within an extended temperature range and is housed in an 8-pin SOIC package.

Feature Summary

• Capacitive coupling architecture for high common-mode transient immunity
• Reinforced insulation rating of 5kVrms for safety-critical isolation
• Single-channel design with dedicated source and sink outputs

Applications

• Industrial motor drives
• Solar inverters
• Uninterruptible power supplies (UPS)

Procurement Notes

Verify the specific suffix 'DWV' against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm that the component status is acceptable for new designs, as availability may vary due to lifecycle changes. Ensure all ordering details match the exact part number to avoid substitution errors.

Selection Notes

Select this component when high isolation voltage and fast switching speeds are required in a compact form factor. The capacitive coupling offers superior performance over optical alternatives in noisy environments. Consider the 8-pin SOIC package constraints and thermal dissipation requirements relative to the 2A/1A drive capability for the target PCB layout.

Part Context

This part belongs to the UCC531x family of isolated gate drivers. It utilizes Texas Instruments' iCoupler or similar capacitive isolation technology. The series is designed to replace traditional optocouplers in applications demanding higher reliability and faster data rates. It serves as a bridge between low-voltage control logic and high-power switching devices.

Replacement Considerations

Check for direct substitutes such as the UCC5310MCDWR or other variants in the UCC531x series. Verify pin compatibility and insulation ratings before substituting. Note that some variants may have different packaging or temporary obsolescence statuses.
