Three-phase Full-wave Fan Motor Driver - BD6346FV

BD6346FV is a three phase, sensorless motor 1chip driver with integrated power DMOS MOSFETs. Its feature is sensor-less drive which doesn’t require a hall device as a location detection sensor. Furthermore, introducing a PWM soft switched driving mechanism achieves silent operations and low vibrations.
