DRV8323SRTAT

Overview

The DRV8323SRTAT is a three-phase smart gate driver from Texas Instruments, designed for brushless DC motor applications. It integrates three half-bridge drivers with a charge pump and linear regulator, supporting N-channel MOSFETs within a 6 V to 60 V supply range. The device features an output current of 1 A and operates between -40°C and +125°C. Key integrated functions include three bidirectional current sense amplifiers and SPI/I2C interface capabilities. Packaged in a WQFN-40 format, it enables compact motor control designs by reducing external component count.

Feature Summary

• Smart gate drive architecture allows dynamic adjustment of gate drive output current strength to control power MOSFET switching speed.
• Integrated three bidirectional current sense amplifiers monitor current levels via low-side shunt resistors for each half-bridge.
• Supports both standard serial peripheral interface (SPI) and hardware management interfaces for configuration and fault diagnostics.

Applications

• Brushless DC (BLDC) motor drives
• Three-phase AC induction motor systems
• Compact industrial motion control platforms
