[0019] Please refer to Figure 1A , which is a top view of an electronic device according to a first embodiment of the present invention. This embodiment is described by taking the electronic device 200 as an example, and the electronic device 200 is, for example, a computer host. The electronic device 200 includes a circuit board 210 , a north bridge chip 220 , a south bridge chip 230 and a chip protection system 240 . The chip protection system 240 includes a first temperature sensing element 241 , a judging unit 245 and a protection circuit 247 . The judging unit 245 is electrically connected to the first temperature sensing element 241 and the protection circuit 247 . The diagrams in this embodiment omit some elements, and show the elements in a relatively exaggerated manner, so as to clearly show the technical characteristics of the present invention.

Abstract

The invention provides a chip protection system, an electronic device using the chip protection system, and a chip protection method. The chip protection system is arranged in the electronic device which comprises a circuit board, a north bridge chip and a south bridge chip, wherein, the circuit board is provided with an upper surface and a lower surface which are opposite; both the north bridge chip and the south bridge chip are configured on the upper surface. The chip protection system comprises a first temperature sensing element, a judging element and a protection circuit, wherein, the first temperature sensing element is arranged on the lower surface of the circuit board and below either the north bridge chip or the south bridge chip so as to sense temperature of the north bridge chip or the south bridge chip; the judging unit is used for generating a temperature value according to the state of the first temperature sensing element and comparing the temperature value with a preset value. When the temperature value is higher than the preset value, the judging unit outputs a control signal to the protection circuit so as to switch off the electronic device by the protection circuit.

Description

technical field [0001] The present invention relates to a chip protection system and an electronic device using the same and a chip protection method, and in particular to a chip protection system for protecting at least one of a north bridge chip and a south bridge chip and an electronic device using the same Device and chip protection method. Background technique [0002] Generally speaking, a central processing unit (Central Processing Unit, CPU), a north bridge chip (north bridge chip) and a south bridge chip (south bridge chip) are assembled on the motherboard of the computer. The central processing unit communicates with peripheral components through the north bridge chip and the south bridge chip. Therefore, the north bridge chip and the south bridge chip are important components when the CPU operates. [0003] Currently, with the execution of overloaded programs and the demand for data processing speed, the load on the central processing unit increases relatively. ...
