Overview
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.
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 A...
