Abstract

A display circuit of overheated motherboard includes a function chip and a temperature-controlling chip, which connects to the function chip, the display circuit of overheated motherboard also includes a switching circuit and a LED, the in port of the switching circuit connects to the temperature-controlling chip and receives signal sent by the temperature-controlling chip, the out port of the switching circuit connects to both a first high voltage and the cathode of the LED, the anode of the LED connects to a second high voltage. When the temperature of the function chip surpasses the system hypothesis temperature, this temperature-controlling chip sends out periodic high-low pulse signal to control the switching circuit and the LED flashes on and off in turn accordingly.
