DRV10974 3-Phase Sensorless Motor Driver
Texas Instruments DRV10974 3-Phase Sensorless Motor Driver comes with integrated power MOSFETs, providing continuous drive current up to 1A (rms). The device is designed for cost-sensitive, low-noise, and low-external-component-count applications. The DRV10974 uses a proprietary sensorless control scheme to provide dependable commutation. The 180° sinusoidal commutation significantly reduces pure tone acoustics, typical with 120° (trapezoidal) commutation. The DRV10974 spin-up is configured using a single external low-power resistor. An external low-power resistor can set the current limit. The Texas Instruments DRV10974 device provides simple motor speed control by applying a PWM input to control the magnitude of the drive voltage. It can also be done by driving the PWM pin with an analog voltage and monitoring the FG pin for speed feedback.
