5-V, 3-Phase, Sensorless, Brushless DC Motor Driver  - DRV10866

DRV10866 (ACTIVE)

5-V, 3-Phase, Sensorless, Brushless DC Motor Driver

Description

DRV10866 is a three 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 over-current 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 ½ FG to indicate motor speed with open drain output. A 150° sensorless BEMF control scheme is implemented for a three 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.
