The DRV10974RUMR from Texas Instruments is a 3-phase, sensorless BLDC motor driver designed for cost-sensitive applications. It integrates power MOSFETs and offers a continuous drive current of 1A (rms) and a peak current of 1.5A.
This driver operates with an input voltage range of 4.4V to 18V and features sinusoidal commutation for optimal acoustic performance. Key functionalities include resistor-configurable lead angle, current limit, soft start, and acceleration profile. It also incorporates built-in current sense, eliminating the need for an external sense resistor.
The device is housed in a 16-WQFN (4x4 mm) package and is suitable for surface mounting. It operates within an ambient temperature range of -40°C to 125°C. Protection features include motor-lock detect, overcurrent, short-circuit, overtemperature, and undervoltage protection.
