BD6971FS - Multifunction Single-phase Full-wave Fan Motor Driver

General Description

BD6971FS is a 1chip driver that composes H-bridge of power DMOS FET.

Moreover, it is possible to correspond to 5V class motor because it starts from 3.5V.

Package SSOP-A16 W (Typ.) x D (Typ.) x H (Max.) 6.60mm x 6.20mm x 1.71mm

Key Features

  • Driver including power DMOS FET.
  • Speed controllable by DC / direct PWM input.
  • PWM soft switching.
  • Quick start.
  • Current limit.
  • Lock protection and automatic restart.
  • Rotation speed pulse signal (FG) output SSOP-A16.
