Description
The FAN8460MTC/FAN8460MP is a single phase BLDC
motor driver with variable speed control using output direct
PWM method and it’s typical application is DC cooling fans
with wide range of supply voltage(5/12/24V). This approach
eliminates the need for external pass devices such as BJT,
MOSFET. This solution also offers other advantages over
commonly used external PWM turning fan’s power on and
off at fixed frequency. The external PWM increas stress on
fan and needs level translation in speed and alarm output
because these outputs share the fan’s negative terminal.
In case of CPU cooling, digital controller can give speed
control command with PWM signal adjusting the duty. If a
system has no digital controller, the NTC thermistor input
mechanism can control fan speed with local or ambient tem-
perature sensing.These two kinds of input schemes can meet
various system requirements and applications.
