UCC23313BQDWYQ1

Overview

The UCC23313BQDWYQ1 is an automotive-grade, single-channel optically isolated gate driver designed for high-voltage power switching applications. It features a 3.75 kVRMS basic isolation rating and supports SiC MOSFETs with a 4 A source and 5 A sink output current capability. The device operates within a supply voltage range of 15 V to 30 V and functions across a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 105 ns, a rise time of 28 ns, and a fall time of 25 ns. It is housed in a SOIC-6 package with a power dissipation rating of 750 mW.

Feature Summary

• Provides robust 3.75 kVRMS basic isolation for safe operation in high-voltage environments.
• Delivers strong drive strength with 4 A source and 5 A sink currents suitable for wide-bandgap semiconductors.
• Features fast switching performance with low propagation delay and transition times.
• Designed for automotive reliability with extended operating temperature ranges.

Applications

• Silicon Carbide (SiC) MOSFET gate driving in electric vehicle inverters
• High-frequency DC-DC converters requiring galvanic isolation
• Industrial motor drives and traction systems

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive qualification status against the latest Texas Instruments datasheet. Ensure the SOIC-6 package variant matches your PCB footprint requirements. Confirm humidity sensitivity classification and reflow soldering profile compliance prior to assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when high isolation voltage and fast switching are required for SiC-based designs. The single-channel configuration simplifies layout compared to dual-channel alternatives. Consider the 15 V to 30 V supply range compatibility with standard bootstrap or isolated power supplies. Evaluate the thermal performance given the 750 mW dissipation limit in the SOIC-6 package.

Part Context

This device belongs to the UCC23313 family of optically isolated gate drivers from Texas Instruments. It serves as a bridge between low-voltage control logic and high-voltage power stages. The Q1 designation indicates it meets automotive quality standards, distinguishing it from commercial variants within the same functional family.

Replacement Considerations

The UCC23313BQDWYRQ1 is a reel-packaged version of the same core device. Verify pinout and electrical specifications match before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
