AN44143A Datasheet 3-phase Brushless Motor Driver

Manufacturer: Panasonic

Overview: DReovcisNioon. . T1A4-EA-06307 Product Standards AN44143A Driver IC for 3-phase Brushless.

General Description

 AN44143A is a driver IC for 3-phase brushless motor optimized for fan motors.

By employing the rotor position detector and sine wave PWM drive by 1-Hall-sensor, this IC achieves ponent reduction and miniaturization of motor set as well as motor drive at low noise, low vibration and low powe

Key Features

  • Supply voltage range: 4.5 V ~ 26.4 V.
  • Built-in 5-V regulator.
  • 3-phase full-wave sine-wave PWM drive by 1-Hall-sensor.
  • Selectable Input Mode: Either linear voltage input or PWM input through VSP pin.
  • Selectable the start frequency through SWSF pin.
  • Conduction angle auto driver phase shift correction.
  • Rotation direction selectable (Forward/Reverse).
  • FG pulse divide selectable.
  • Sleep mode.
  • Various protection functions: Under Voltage Lock Out (UVLO).
