Additional Infomation About Product

Datasheet DC Brushless Motor Drivers Multifunction Three-phase Full-wave Fan Motor Driver BD63441AFU General Description Package(s) W(Typ.) x D(Typ.) x H(Max.) BD63441AFU is a three-phase sensorless fan motor SSOP-C20 5.00mm x 6.40mm x 1.35mm driver that is suited for speed controllable fans. It features a sensorless drive which doesnt require a hall device as a location detection sensor. Furthermore, there is a PWM soft switched driving mechanism for silent operation and low vibrations. Features Pre-driver compatible for external Tr. Sensorless drive and PWM soft switching Under voltage lock out (UVLO) Rotational speed control by DC input voltage Current limit Soft start SSOP-C20 Lock protection and automatic restart Quick start Rotational speed pulse signal (FG) output Applications For 12V fan motors for desktop PC, server, and general consumer equipment.
