DRV10983/DRV10983-Q1 Sensorless BLDC Motor Driver

Texas Instruments DRV10983/DRV10983-Q1 Three-Phase Sensorless BLDC Motor Driver is a three-phase sensorless motor driver 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 DRV10983/DRV10983-Q1 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. The DRV10983-Q1 devices are AEC-Q100 qualified for automotive applications.
