3 Description
DRV10866 is a 3- phase, sensorless motor driver with integrated power MOSFETs with drive current capability up to 680-m A peak. DRV10866 is specifically designed for low noise and low external ponent 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...
