Problems solved by technology

[0004] However, if the fan is running for a long time, it will affect the life of the fan, and the fan is always running at the maximum power, making a lot of noise, which affects the customer experience; in the second solution, the temperature control of the fan is added, but the fan is still running at the rated power , there will still be noise problems, and additional software logic control is required, which will increase the processing complexity

Abstract

The invention provides an intelligent fan control circuit based on thermistor control and a terminal system. The intelligent fan control circuit based on thermistor control comprises a triangular wave generation circuit, a thermistor control circuit and a fan control circuit, and the triangular wave generation circuit comprises a first terminal and is used for generating a triangular wave signal; the thermistor control circuit comprises a second terminal and a third terminal, and the second terminal is connected with the first terminal and used for receiving the triangular wave signal and generating a square wave signal; the fan control circuit comprises a fourth terminal and a fifth terminal, and the fourth terminal is connected with the third terminal and used for receiving the square wave signal, controlling connection and disconnection between the fourth terminal and the fifth terminal according to the square wave signal and outputting voltage to control a fan.

Description

technical field [0001] The present application relates to the field of intelligent terminals, and in particular, to an intelligent fan control circuit and terminal system based on thermistor control. Background technique [0002] At present, most of the smart terminals with multi-channel video capture function have a heating power of more than 10W. Therefore, smart terminals are often equipped with fans to actively dissipate heat, so that the smart terminals can work more stably and reliably. For smart terminals with hard disk storage function, due to cost control, consumer-grade hard disks are mostly used in the market. For consumer-grade hard disks, if the operating temperature exceeds 65 °C, the working life and stability of the hard disk will be affected. Therefore, the use of fans for active heat dissipation is beneficial to prolong the life and reliability of smart terminals and hard disks. [0003] At present, the common solutions on the market using fans for heat di...
