Two Phase Dual-coil High Voltage Smart Fan Motor Driver
General Description
Features
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.
AH9280
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
ESD Rating: 6000V (Human Body Model)
400V (Machine Model)
Applications
•
•
•
•
When there is no motion for one second, the IC will
automatically detect the locked rotor conditions, and
enter protection mode, shutting off the motor driver
for five seconds. Then, the IC will turn on the motor
driver for one second to detect whether there is
rotation condition, if fails, the IC will shut off motor
driver for five seconds again. This sequence will be
repeated until rotation condition is detected, and the
IC enters normal operation. This feature can
effectively prevent the AH9280 from overheating and
damage due to long-time locked rotor condition.
5V/12V DC Brushless Motor/Fan
PC, Server, Laptop Cooling Fan
