Temperature sensors are devices that measure temperature and transform it into a readable form for data collection. They are available in two main types: analog and digital output. The DS1722U is a temperature sensor that falls into the digital output category. It is an Electronic Thermal Protector (ETP) device with integrated temperature measurement functionality. This sensor has a great variety of application fields and a reliable and efficient working principle.

The DS1722U is an ETP device with I2C (Inter-Integrated Circuit) interface. It offers enhanced temperature protection capabilities, high performance and flexibility, and rapid response times at an affordable price. It is well suited for temperature control and blow-off of cooling fans, protection of battery packs, and many other applications. It features an external power supply, adjustable temperature trip point (TTP) up to 150°C, 40°C hysterisis, and an integrated temperature measurement comparator. All of this adds up to a reliable and accurate temperature sensor for various demanding applications.

The working principle of the DS1722U is based on its integrated temperature measurement comparator. It has a measurement input which is directly connected to a temperature sensing element. When the temperature of the sensing element reaches a predefined threshold, the comparator will trigger an interrupt to indicate a temperature trip. This will then activate a protective circuit, such as powering-down the system or signaling other external circuits.

In summary, the DS1722U is a reliable and accurate temperature sensor with a wide range of application fields. Its built-in temperature measurement comparator and its I2C interface make it very easy to use and integrate into most system architectures. Its small form factor and easy to use interface make it a great choice for many temperature control applications. It is capable of providing reliable temperature protection capabilities, high accuracy, rapid response times, and flexible control capabilities for an affordable price.
