DRV8350RSRGZT

Overview

The DRV8350RSRGZT is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor applications. It operates within a supply voltage range of 6 V to 95 V and supports load voltages up to 75 V. The device features an integrated buck regulator with an output voltage range of 9 V to 100 V. It provides three half-bridge outputs with a peak output current of 25 mA per channel. The component utilizes a SPI interface for configuration and control. It is housed in a 48-VQFN package (7x7 mm) and is rated for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-voltage buck regulator to simplify power supply requirements for gate drive circuits.
• Provides dedicated hardware management interfaces alongside digital SPI control for flexible system integration.
• Includes built-in protection mechanisms such as overcurrent protection and thermal shutdown for reliable operation.

Applications

• Brushless DC (BLDC) motor control systems
• Industrial automation drives
• Home appliance motor control

Procurement Notes

Verify the specific suffix 'ZRT' confirms the tape-and-reel packaging format when sourcing. Ensure the ordering part number matches the exact pinout and thermal pad configuration required for the PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component for designs requiring a compact solution with integrated power regulation. The 48-pin QFN package offers a balance between thermal performance and board space efficiency. Consider the 25 mA gate drive capability against the target MOSFET gate charge requirements to ensure adequate switching speeds without excessive external components.

Part Context

This device belongs to the DRV8350R series, which focuses on smart gate driving capabilities for three-phase motors. It distinguishes itself from basic drivers by including internal regulation and advanced protection features. The R-series designation typically indicates specific packaging or material configurations within the broader product family.

Replacement Considerations

The DRV8350RSRGZR is a parameter-equivalent alternative available in reel packaging. Designers should verify that any substitute maintains identical pin compatibility and electrical specifications before implementation.
