UCC23513BQDWYRQ1

Overview

The UCC23513BQDWYRQ1 is an automotive-grade, optically isolated single-channel gate driver designed for IGBT, MOSFET, and SiC MOSFET applications. It features a peak output current of 4.5A source and 5.3A sink, with a supply voltage range of 14V to 33V. The device provides 5.7kVrms reinforced isolation and supports high-side and low-side configurations. Key electrical parameters include a maximum propagation delay of 105ns, rise time of 28ns, and fall time of 25ns. It operates within a junction temperature range of -40°C to +150°C and is housed in an extended SOIC-6 package.

Feature Summary

• Optically isolated input interface with ediode technology for enhanced reliability and aging resistance compared to standard LEDs
• High common-mode transient immunity (CMTI) of 150kV/μs minimum to ensure robust performance in noisy environments
• Extended SO-6 package design offering creepage and clearance distances greater than 8.5mm for improved safety margins
• Automotive qualification compliant with AEC-Q100 standards for reliable operation under harsh thermal conditions

Applications

• Motor drive systems requiring high-reliability isolation
• Solar inverters utilizing IGBT or SiC power switches
• Industrial power supplies and converters
• Appliance control circuits demanding long-term stability

Procurement Notes

Verify that the specific suffix 'BQDWYRQ1' matches the required automotive grade and reel packaging specifications. Confirm that the device meets the necessary AEC-Q100 qualification requirements for your target application environment. Ensure compatibility with existing PCB footprints and isolation barrier ratings before finalizing procurement orders.

Selection Notes

Select this component when high CMTI and optical isolation are preferred over capacitive alternatives for noise immunity. It is suitable for designs requiring a wide supply voltage range up to 33V for driving SiC devices. Consider the extended SO-6 package dimensions and thermal characteristics to ensure adequate board space and heat dissipation for the intended power management IC implementation.

Part Context

This part belongs to the UCC23513 series of optically isolated gate drivers from Texas Instruments. It serves as a direct pin-to-pin upgrade for traditional optocoupler-based gate drivers, offering superior performance metrics while maintaining layout compatibility. The series is engineered to replace legacy components in motor drives and industrial power applications where reliability and speed are critical.

Replacement Considerations

The UCC23513DWYR is a non-automotive equivalent within the same family. Verify if automotive qualification is mandatory; otherwise, the standard version may be considered. Ensure that any substitute maintains the same SOIC-6 footprint and isolation voltage ratings to preserve circuit integrity.
