Data Sheet Two Phase Dual-coil High Voltage Smart Fan Motor Driver AH9280 General Description The AH9280 is a most advanced smart fan controller and Hall IC driver manufactured by special CMOS process. It is designed for 5V and 12V cooling fan. To allow survival in a harsh environment and lower the total system cost, the AH9280 has been designed with many powerful functions while almost eliminating all discrete components, such as, capacitor, resistor, transistor, diode and PC board. The AH9280 can operate normally in an ambient temperature up to 125°C due to its Hall IC circuitry and power MOSFET output that allow low power dissipation.
