Said temperature detection unit includes first and second current source, selection circuit, temperature-sensing element and amplification circuit. Besides, said invention also provides their connection mode and concrete action of the above-mentioned every component.

Description

technical field [0001] The present invention relates to temperature detection, and in particular to a temperature detection unit and system for switching current. Background technique [0002] In some occasions, we have to monitor temperature changes. For example, in the current development trend of science and technology, the operating frequency of the central processing unit (Central Processing Unit, CPU), graphics processing unit (Graphics Processing Unit, GPU) and their peripheral circuits is constantly increasing, and the first problem that bears the brunt is the working time. The heat emitted is also increasing. In order to ensure that the above-mentioned central processing unit, graphics processing unit and their peripheral integrated circuits (Integrated Circuit, IC) can work normally and not be burned due to high temperature, temperature monitoring has become a very important thing. [0003] There will be a hardware monitoring IC (Hardware Monitor IC) on the gener...
