DRV10983PWP .

The DRV10983PWP is a 3-phase sensorless brushless DC Motor Controller with integrated power MOSFETs, which can provide continuous drive current up to 2A. The device is specifically designed for cost-sensitive, low-noise/low external component count applications. The motor controller uses a proprietary sensor-less 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, analogue or I²C inputs. Motor speed feedback is available through either the FG pin or I²C. The motor controller features an integrated buck/linear regulator to efficiently step down the supply voltage to either 5 or 3.3V for powering both internal and external circuits. The device is available in either a sleep mode or a standby mode version to conserve power when the motor is not running.
