DRV10866 is a 3- phase, sensorless motor driver with integrated power MOSFETs with drive current capability up to 680-mA peak. DRV10866 is specifically designed for low noise and low external component count fan motor drive applications. DRV10866 has built-in overcurrent protection with no external current sense resistor needed. The synchronous rectification mode of operation achieves increased efficiency for motor driver applications. DRV10866 outputs either FG or 1⁄2 FG to indicate motor speed with open-drain output. A 150° sensorless BEMF control scheme is implemented for a 3-phase motor. DRV10866 is available in the thermally efficient 10-pin, 3-mm × 3-mm × 0.75-mm SON (DSC) package. The operating temperature is specified from –40°C to 125°C.

TIDA-00112 — 가변 속도 제어를 지원하는 5V, 3상, 무센서 모터 시스템
This reference design provides a simple way to spin and control a 5V, 3-phase, BLDC fan motor with minimum development time and overhead. It utilizes the DRV10866, a sensorless BLDC motor driver, for the power stage and a TLC555 timer to provide a variable duty cycle PWM signal for speed control. (...)
