DRV10975 Sensorless BLDC Motor Controllers Texas Instruments DRV10975 Sensorless BLDC Motor Controllers are a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 1.5A. Each device is specifically designed for cost-sensitive, low-noise/low external component count applications. These devices use a proprietary sensorless control scheme to provide continuous sinusoidal drive. They significantly reduce the pure tone acoustics that typically occur as a result of commutation. The Texas instruments DRV10975 controller features an integrated buck/linear regulator to efficiently step down the supply voltage to either 5V or 3.3V for powering both internal and external circuits. They are available in either a sleep mode or a standby mode version to conserve power when the motor is not running. The standby mode (4.5mA) version leaves the regulator running and the sleep mode (80µA) version shuts it off. It is recommended to use the standby mode version in applications where the regulator is used to power an external microcontroller.
