摘要： A low-pin count fan speed control system and a method thereof include primarily an activation unit to drive a fan to operate. When the fan starts completely, the fan slows down to a pre-determined rotation speed through an idle speed regulation unit. After achieving a pre-determined temperature through a temperature transition unit, the fan speed beings to increase from the idle speed. When the fan is operating, the rotation speed is properly increased in proportion to the temperature, using a positive temperature regulation slope unit. Therefore, through this method, the rotation speed will not be decreased by foreign objects when the fan is operating and a computer host can be provided with proper heat dissipation.

摘要： A single-pin multifunctional device and method for input and output in controlling a direct-current fan use a control chip to control an operation of the fan, thereby protecting issues generated by too high a temperature. The control chip uses a value of a temperature induction unit to determine a range of protection and maintains the fan at an idle speed operation through an idle speed regulation unit. Meanwhile, the temperature induction unit notifies an over-temperature protection unit to switch from the idle speed regulation unit to the over-temperature protection unit. Therefore, the fan is controlled through a single pin to input and output simultaneously.
