Overview
The DRV10983PWP, manufactured 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 requiring low noise and a minimal number of external components. It features integrated power MOSFETs, enabling continuous drive currents up to 2 A and peak currents up to 3 A. The DRV10983PWP uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, significantly reducing pure tone acoustics associated with commutation.
