DRV8323HRTAT

Overview

The DRV8323HRTAT 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 60 V and supports an absolute maximum rating of 65 V. The device features six high-side and low-side drivers with a peak output current of 1 A. It utilizes a WQFN-40 package and includes integrated current sense amplifiers. The component functions across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates hardware management interface for direct control without microcontroller dependency
• Includes built-in current sense amplifiers for phase current monitoring
• Supports smart gate drive architecture with adjustable slew rate and dead-time control

Applications

• Brushless DC (BLDC) motor drives
• Three-phase inverter systems
• Industrial automation motor control

Procurement Notes

Verify the specific suffix 'HRTAT' against the manufacturer datasheet to confirm pinout and feature set alignment. Ensure the ordering part number matches the required package type and thermal performance specifications for the target application environment.

Selection Notes

Select this component when a dedicated three-phase gate driver with integrated current sensing is required. It is suitable for designs needing hardware-based control interfaces or SPI/I2C programmability. Consider the WQFN-40 package constraints and thermal dissipation requirements relative to the expected load currents.

Part Context

This part belongs to the DRV8323 family of smart gate drivers. It shares architectural similarities with other variants in the series but differs in packaging and specific interface configurations. The HRTAT designation indicates a specific reel and tape configuration within the standard product line.

Replacement Considerations

DRV8323HRTAR is a compatible alternative within the same package family.
