Introduction to MAX6687AU75H+T Application Field and Working Principle

Temperature sensors are essentially devices that measure the temperature or the change in temperature. They are widely used in a broad range of areas including industrial automation, communication, consumer electronics, medical, automotive, and even aerospace. As a type of temperature sensor, thermostats, as its name suggests, function as temperature control devices that detect and control the temperature. Amongst thermostats, solid state is one of the main types. This article will discuss the application field and working principle of MAX6687AU75H+T, a kind of temperature sensor, thermostat and solid state.

Application Field of MAX6687AU75H+T

The MAX6687AU75H+T is a low-power digital thermal monitoring device that is specially designed for mobile and desktop PCs. It is optimized for Intel Processors with Thermal Monitor 2 feature. In mobile PCs, it can detect the processor temperature every 1.25 seconds and generate thermal-event warnings when temperature exceeds specified thresholds. In desktop PCs, it can perform temperature monitoring and aggressive fan control in movie, idle, and active modes. Additionally, MAX6687AU75H+T can be adapted for other applications such as temperature and over-temperature monitoring in IoT and home appliances, as well as thermal protection in motor control and energy management.

Working Principle of MAX6687AU75H+T

The MAX6687AU75H+T device combines on-chip temperature sensor, thermal limit comparator, and patrol functions in a single 16-pin package. The internal temperature sensor contains an on-chip resistor that changes with temperature, allowing for accurate temperature measurement. This device takes a voltage-proportional signal from its thermal sensor that is proportional to temperature and compares it to preset high and low warning/critical temperatures set in the MAX6687EUA register. The thermal-event output will be triggered as soon as the temperature reaches the preset thresholds. The thermal patrol function is suitable for desktop PCs and helps to decrease fan noise, saving power and prolonging fan life. When the device is in thermal patrol mode, it performs regular temperature checks and issues temperature-polling commands. When the temperature of the processor drops below a preset temperature, the cooling fan is regulated to varying speeds according to the temperature difference between the current temperature and the preset temperature.

Conclusion

In conclusion, MAX6687AU75H+T is a low-power digital thermal monitoring device optimized for Intel Processors with Thermal Monitor 2 feature. It can detect processor temperature quickly and provide thermal-event warnings with adjustable high and low thresholds. Additionally, MAX6687AU75H+T can be adapted for other applications such as temperature and over-temperature monitoring in IoT and home appliances, as well as thermal protection in motor control and energy management. Its thermal patrol function is suitable for desktop PCs, reducing fan noise and saving power.
