The device is specifically designed for cost-sensitive, lownoise, low-external-component-count applications.
The DRV10983 device uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which significantly reduces the pure tone acoustics that typically occur as a result of commutation.
The interface to the device is designed to be simple and flexible.
The motor can be controlled directly through PWM, analog, or I2C inputs.
Motor speed feedback is available through either the FG pin or I2C.
