Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design DRV10974 SLVSDN2C – JANUARY 2018 – REVISED SEPTEMBER 2018 DRV10974 12-V, Three-Phase, Sensorless BLDC Motor Driver.

General Description

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.

Key Features
