Abstract
A protection device for a micro-controller chip comprising a heat sink, a cooling fan, and an overheat alarm. The heat sink is adapted to be mounted on a micro-controller chip and is capable of dissipating heat generated by the micro-controller chip. The cooling fan disperses the heat dissipated by the heat sink into the surrounding atmosphere. The overheat alarm includes a temperature sensor, a voltage comparator, an oscillator, and alarm sound generator. The temperature sensor converts a temperature of the heat sink into electrical signals and outputs a voltage proportional to the temperature of the heat sink. A voltage comparator compares the voltage output from the temperature sensor with a reference voltage signal and outputs a comparator output voltage. The oscillator generates and outputs an oscillating voltage signal. The alarm sound generator is enabled by the comparator output voltage from the voltage comparator for generating an alarm sound by operating a speaker in accordance with the input oscillating voltage signal from the oscillator.
