UCC27211AQDDARQ1

Gate Driver Overview

The UCC27211AQDDARQ1 is an automotive-grade half-bridge MOSFET gate driver from Texas Instruments, designed for high-frequency switching applications. It features a peak output current of 3.7 A source and 4.5 A sink, enabling rapid switching transitions with rise and fall times of 7.2 ns and 5.5 ns respectively. The device operates within a supply voltage range of 8 V to 17 V and supports non-inverting logic inputs compatible with CMOS and TTL standards. It includes a built-in bootstrap diode rated for 120 V common-mode transient immunity and functions reliably across an extended temperature range from -50°C to +150°C.

Gate Driver Feature Summary

• Integrated 120-V bootstrap diode eliminates external component requirements for high-side drive biasing.
• High peak output current capability ensures fast switching speeds and reduced power dissipation in power switches.
• Robust common-mode transient immunity supports operation in noisy environments typical of automotive power electronics.

Gate Driver Applications

• Automotive DC-DC converters
• On-board charger (OBC) systems
• Motor control circuits

Gate Driver Procurement Notes

Verify the specific suffix 'AQDRQ1' corresponds to the AEC-Q100 qualified automotive grade variant with SOIC-8 packaging. Confirm that the ordering part number matches the required temperature rating and package type before finalizing procurement orders to ensure compliance with automotive design specifications.

Gate Driver Selection Notes

Select this component when designing isolated or non-isolated gate drive stages requiring high peak current and integrated bootstrap functionality. It serves as a direct upgrade to legacy drivers like the UCC27201, offering improved current drive capabilities while maintaining pin compatibility for many existing designs.

Gate Driver Part Context

This device belongs to the UCC2721xA family of high-voltage half-bridge drivers. It is specifically engineered for automotive reliability, meeting AEC-Q100 standards. The Q1 suffix denotes its qualification for automotive use, distinguishing it from commercial variants within the broader UCC2721x product line.

Gate Driver Replacement Considerations

The UCC27211A-Q1 is the commercial/automotive equivalent without the specific reel/cut-tape suffix variations. Verify pinout compatibility if substituting with other members of the UCC272xx series.
