AH9282 - Two Phase Dual-coil High Voltage Smart Fan Motor Driver

Download the AH9282 datasheet PDF. This datasheet also covers the AH9281 variant, as both devices belong to the same two phase dual-coil high voltage smart fan motor driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The AH9281/82 is a one-chip solution for driving two-coil brushless DC motors and fans.

Based on the advanced CDMOS process, the IC contains a Hall-effect sensor, dynamic offset correction and powerful output drivers with 1200mA peak output current capability.

Key Features

  • High Sensitivity Integrated Hall Sensor.
  • Low Start-up Voltage.
  • 5V and 12V Operation.
  • Peak Output Current up to 1200mA.
  • Power Efficient CMOS and Power MOSFETs.
  • Built-in Output Protection Clamping Diode.
  • Locked Rotor Shutdown and Auto-restart.
  • Integrated Tachometer (AH9281) or Alarm (AH9282) Signal Output.
  • ESD Rating: 6000V (Human Body Model) 400V (Machine Model).

Data Sheet Two Phase Dual-coil High Voltage Smart Fan Motor Driver with FG/RD AH9281/82 General Description The AH9281/82 is a one-chip solution for driving two-coil brushless DC motors and fans. Based on the advanced CDMOS process, the IC contains a Hall-effect sensor, dynamic offset correction and powerful output drivers with 1200mA peak output current capability. Specially designed for driving large fans, the device is optimized for low start-up voltage. Frequency Generator or Rotation Detection is available. The open drain output makes easier the connectivity with any external interface such as hardware monitoring or Super I/O IC. The AH9281/82 is available in TO-95 and SOT-89-5 packages.
