Multifunction Three-phase Full-wave Fan Motor Driver - BD63441AFU

BD63441AFU is a three-phase sensorless fan motor driver that is suited for speed controllable fans. It features a sensorless drive which doesn’t require a hall device as a location detection sensor. Furthermore, there is a PWM soft switched driving mechanism for silent operation and low vibrations.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
