Description

General part information

DRV10974 Series

The DRV10974 device is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 1 A (rms). The device is designed for cost-sensitive, low-noise, and low-external-component-count applications.

The DRV10974 device uses a proprietary sensorless control scheme to provide dependable commutation. The 180° sinusoidal commutation significantly reduces pure tone acoustics that are typical with 120° (trapezoidal) commutation. The DRV10974 spin-up is configured using a single external low-power resistor. The current limit can be set by an external low-power resistor.

The DRV10974 device provides for simple control of motor speed by applying a PWM input to control the magnitude of the drive voltage, or by driving the PWM pin with an analog voltage and monitoring the FG pin for speed feedback.
