DRV8312DDW TI Motor Driver | 44-HTSSOP | 3-Phase, 50V, 3.5A

Product Overview

The DRV8312DDW is a three-phase brushless DC (BLDC) motor driver from Texas Instruments, designed for high-performance motor control applications. It integrates three half-bridge drivers with a maximum supply voltage of 50V and continuous output current of 3.5A per channel. The device is housed in a 44-pin HTSSOP package with an exposed pad for enhanced thermal dissipation. It features independent control of each phase, making it suitable for sensorless or sensored field-oriented control (FOC) and trapezoidal commutation. The DRV8312DDW includes protection features such as overcurrent, overtemperature, and undervoltage lockout, ensuring reliable operation in demanding environments.
