  • Cooling Fan Velocity Control Apparatus Using Timer and Temperature Sensor
    Publication number: 20140086758
    Abstract: An apparatus and method for controlling a velocity of a cooling fan using a timer and a temperature sensor in a set-top box (STB) are provided. An apparatus for controlling a velocity of a cooling fan in an STB may include a temperature sensor unit to change a resistor to be in inverse proportion to an internal temperature, using a thermistor, a timer unit to generate a pulse signal using a capacitor and the resistor of the temperature sensor unit, a switching unit to turn on/off applied voltage, using the generated pulse signal, and a power source unit to apply the voltage to the switching unit.
