Application Field

With its wide operating temperature range and low operating current, the MAX6699EE34+T is an ideal solution for general precision temperature sensing applications. The low power operation and small package size make it suitable for battery operated applications, while its high accuracy makes it suitable for precision temperature control. Typical applications of the MAX6699EE34+T include industrial temperature control, automotive temperature sensing and protection, surface mount soldering temperature control, and consumer applications. It is available in commercial grade (0°C ~ +70°C) and automotive grade (-40°C ~ +125°C) options.

Working Principle

The MAX6699EE34+T is an analog and digital output temperature sensor, which uses a thermistor element to measure temperature. The thermistor element is sensitive to temperature and is embedded in a metal package which absorbs heat from the environment. The element, together with an integrated signal conditioning circuit, provide an output voltage proportional to the sensed temperature. This signal can then be converted by an external ADC or controller into a digital temperature value for further processing. The output voltage of the MAX6699EE34+T is calibrated over the full operating temperature range, making it accurate and reliable. In addition, the integrated temperature register stores a temperature value which can be read via I2C protocol, providing an additional temperature sensing capability.

The MAX6699EE34+T also has an open-drain digital output pin for temperature warnings or limit detections, allowing for further control applications. This digital output pin can be compared to a user defined temperature limit value, and is triggered when the temperature exceeds the threshold. This allows for the implementation of temperature protection mechanisms in applications.

In summary, the MAX6699EE34+T offers a comprehensive solution for applications which require accurate temperature sensing. The integrated signal conditioning circuit makes it a low-power and low-cost solution, while its accurate calibration and digital output make it suitable for precise temperature control applications.
