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...
