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 temperature sensing.These two kinds of input schemes can meet various system requirements and applications.
