The LMT85LPGM is a three-terminal digital temperature sensor and RTD IC. It is designed from a sensitive high-accuracy temperature detection circuit and a dielectric isolation system with a feedback loop. The main features of the LMT85LPGM include high accuracy, low power consumption, excellent linearity, low cost, low noise and low offset.

The LMT85LPGM temperature sensor IC can be divided into three main categories—Analog, Digital and Fuzzy Logic. The most commonly used Analog versions of the LMT85LPGM sensor IC have a 0.5 V output, but they are not as accurate as the Digital or Fuzzy versions. The Digital versions have an output of 0.5 V and 0.85 V and are more accurate than the Analog versions. Fuzzy Logic versions have a 0.35 V output and are the most accurate of all the versions.

In terms of application fields, the LMT85LPGM temperature sensor is used in a variety of environments and applications such as automotive, power electronics and consumer electronics. Typical applications of the IC include temperature monitoring, overvoltage protection, energy management, HVAC systems and fluid control, among others. The IC is suitable for a wide range of temperature measurement and control applications.

The working principle of the LMT85LPGM temperature sensor is based on the principle of resistance-temperature coefficient (RTC). It uses the RTC of a reliable metal oxide semiconductor (MOS) as the temperature sensing element. The RTC of the MOS is affected by temperature changes, and so the resistance of the MOS changes accordingly. The change in resistance is then converted into an analog electrical signal and is further processed and digitized into a series of signals.

The LMT85LPGM temperature sensor features a wide temperature range from -50°C to 150°C and excellent linearity that makes it suitable for a variety of temperature measurement and control applications. It has a low power consumption that makes it suitable for battery powered applications, and a small size that makes it ideal for portable devices. The IC also has a high output accuracy of ±2°C, and is RoHS compliant.

In conclusion, the LMT85LPGM temperature sensor is a three-terminal digital temperature sensor and RTD IC with a number of advantages and applications. It has excellent linearity, low cost and low noise, and is suitable for automotive, power electronics and consumer electronics applications. The LMT85LPGM\'s working principle is based on the principle of resistance-temperature coefficient (RTC) and it converts the change in resistance into an analog electrical signal. The sensor offers a wide temperature range, low power consumption, and high output accuracy for a number of temperature measurement and control applications.
