Abstract

The invention discloses an over-temperature protection terminal for control of hardware. The over-temperature protection terminal comprises a temperature detection unit, a DC-DC (direct current-direct current) power source chip and a control unit. The temperature detection unit is used for detecting temperature of a to-be-detected system, and converting the detected temperature of the to-be-detected system into a voltage signal. The DC-DC power source chip is used for supplying power for the to-be-detected system. The control unit is used for receiving the voltage signal output from the temperature detection unit and controlling whether to supply power for the to-be-detected system or not. The temperature detection unit, the control unit and the DC-DC power source chip are connected in sequence. The over-temperature protection terminal is used for control of pure hardware, can cut off a main power source of a system directly when the temperature is higher than a preset limit value so as to protect the hardware of the system, and can turn on the power source automatically when the temperature recovers to a reasonable range so that the system can be started to run smoothly and effectively.

Description

technical field [0001] The invention relates to an over-temperature protection terminal, in particular to a hardware-controlled over-temperature protection terminal. Background technique [0002] With the emergence and development of large-scale integrated circuits, heat dissipation and reliability issues of integrated circuits have attracted more and more attention. Because integrated circuits require faster and faster computing speeds and higher frequencies, a large amount of heat loss will inevitably be generated; moreover, the parameters of integrated circuit resistors, capacitors, and transistors are greatly affected by temperature. If the temperature of the system cannot be well controlled, the system will not work normally and efficiently. [0003] A large number of studies have focused on the temperature control problem when the system is working, and there are few studies on how to protect the system after the temperature exceeds the controllable range, especially ...
