Abstract

The invention provides an overheating protection device and method of an electronic device. The method of the invention comprises the following steps: testing the temperature value and temperature variation slope of the electronic device; if the temperature variation slope is more than a preset slope or the temperature value is more than a temperature boundary value during a preset time after starting the electronic device, stopping the operation of the electronic device. By adopting the method of the invention, the temperature anomaly of the electronic device can be found early so as to effectively prevent the overheating of the electronic device.

Description

technical field

[0001] The invention relates to an overheat protection device and method for an electronic device, and in particular to an overheat protection method for temperature monitoring of an electronic device. Background technique

[0002] With the advancement of integrated circuit design and semiconductor manufacturing process, the speed of microprocessor processing data is getting faster and faster, but with the complexity of integrated circuits, the heat generated by microprocessors is also increasing. It will affect its working efficiency and reduce its service life, and even cause the computer to crash in severe cases. In order to avoid the occurrence of the above situation, the heat protection mechanism of the microprocessor generally only designs a temperature boundary value. When the temperature rises to the boundary value, the operating frequency is reduced to avoid the microprocessor from overheating. Although this mechanism provides a preventive microproce...
