BD6346FV - Three-phase Full-wave Fan Motor Driver

Description

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.

Features

  • Integrated Power DMOS FET driver.
  • Sensorless PWM soft switched drive.
  • Lock protection and automatic restart.
  • DC voltage/direct PWM input ,speed control.
  • Current limit.
  • Soft-Start function.
  • Quick-Start function.
  • Rotating speed pulse signal(FG)output.
  • UVLO Package(s) SSOP-B20 W (Typ. ) x D (Typ. ) x H (Max. ) 6.50mm x 6.40mm x 1.45mm SSOP-B20.
