DRV10866DSCR

The DRV10866DSCR is a 3-phase sensorless brushless DC Motor Driver with integrated power MOSFETs. DRV10866 is specifically designed for low noise and low external component count fan motor drive applications. Motor drive 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. Motor driver outputs either FG or 1/2 FG to indicate motor speed with open-drain output. A 150° sensor-less BEMF control scheme is implemented for a 3-phase motor.
