UCC23313QDWYRQ1

Overview

The UCC23313QDWYRQ1 is an automotive-grade, single-channel optically isolated gate driver from Texas Instruments. It provides 3.75-kVRMS isolation and supports output currents of 4 A (source) and 5 A (sink). The device operates within a supply voltage range of 15 V to 30 V and features a maximum propagation delay of 105 ns. Key timing parameters include 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 and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides 3.75-kVRMS single-channel isolation for high-voltage applications
• Features opto-compatible input design for pin-to-pin replacement of optical isolators
• Delivers robust 4-A source and 5-A sink output drive capability
• Supports high-speed switching with low propagation delay and fast rise/fall times

Applications

• Automotive motor control systems
• Inverter bridge drivers
• High-side and low-side gate driving
• Industrial power conversion

Procurement Notes

Verify the specific suffix 'QDWYRQ1' against official Texas Instruments documentation to confirm automotive qualification and tape-and-reel packaging configuration. Ensure compatibility with system isolation requirements and thermal management needs given the 750 mW dissipation limit. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when replacing existing optocoupler-based gate driver designs with a higher performance alternative. It is suitable for applications requiring robust galvanic isolation and high peak current drive. Consider the SOIC-6 footprint constraints and ensure the PCB layout supports the required isolation creepage and clearance distances for the 3.75-kVRMS rating.

Part Context

This part belongs to the UCC23313 family of optically isolated gate drivers. It is designed as a drop-in upgrade for traditional opto-isolated solutions, offering improved speed and drive strength while maintaining compatibility with standard optocoupler pinouts. The Q1 suffix indicates automotive grade qualification under AEC-Q100 standards.

Replacement Considerations

Direct pin-to-pin replacements include other variants within the UCC23313 family, such as UCC23313BQDWYRQ1. Verify that substitute parts match the specific isolation voltage and drive current requirements of the original design.
