Overview
The DRV10983PWPR, produced by Texas Instruments, is a 24-V nominal, 3-phase sensorless sinusoidal control BLDC (Brushless DC) motor driver. This device is designed for cost-sensitive applications that require low noise and a minimal number of external components. It features integrated power MOSFETs, capable of providing continuous drive current up to 2 A and peak current up to 3 A. The DRV10983 uses a proprietary sensorless control scheme to deliver continuous sinusoidal drive, significantly reducing pure tone acoustics associated with commutation.
The device offers a flexible interface, allowing motor control through PWM, analog, or I2C inputs. It also includes a dedicated SPEED pin for accepting either analog or PWM input, a FG pin for providing tach feedback, and a DIR pin for forward-reverse control. Additionally, it has an integrated step-down regulator to efficiently provide voltage (5 V or 3.3 V) for internal and external circuits.
