Texas Instruments DRV10964 Sensorless BLDC Motor Driver
Texas Instruments DRV10964 Sensorless BLDC Motor Driver is a three-phase sensorless motor driver with integrated power MOSFETs. It is specifically designed for high-efficiency, low noise, and low external component count motor drive applications. The proprietary sensorless windowless 180° sinusoidal control scheme offers ultra-quiet motor drive performance. The DRV10964 contains an intelligent lock detect function and other internal protection circuits to ensure safe operation. The Texas Instruments DRV10964 is available in a thermally efficient 10-pin USON package with an exposed thermal pad.Features
