Temperature Sensors - PTC Thermistors offer a versatile way to measure temperature in various applications. The USP17957 PTC Thermistor is a temperature sensing device that can measure temperatures from -55C to +175C. It is a one-wire device which contains a self-heating element to compensate for variations in temperature. It can be connected to the same bus as other temperature sensors, eliminating the need for multiple cables.

The USP17957 PTC Thermistor is designed to offer high accuracy temperature measurement through the use of a voltage regulator which controls the thermistor. The voltage regulator will adjust the impedance of the thermistor to keep the temperature within a specific range. Additionally, the self-heating element is used to offset bias voltage fluctuations. This ensures that the device remains accurate over a wide range of temperatures.

The working principle of the USP1795 PTC Thermistor is based on a change in resistance when the temperature changes. The thermistor has a positive temperature coefficient (PTC) which results in an increase in resistance as the temperature increases. The resistance is measured across the device using a voltage regulator. The voltage regulator will adjust the voltage across the device to ensure the resistance remains within a specified range. The voltage regulator is used to maintain the accurate temperature measurement across a wide range of temperatures.

The USP17957 PTC Thermistor is an ideal solution for applications requiring accurate temperature measurements over a wide range of temperatures. It is suitable for applications such as automotive, HVAC, and energy management. Additionally, the device is durable and reliable, making it a great choice for long-term projects. The device is also easy to install and has low power consumption, making it an attractive solution for applications that are sensitive to power consumption.

The USP17957 PTC Thermistor is an effective solution for temperature measurement applications. It offers high accuracy and is suitable for use in a variety of applications. Additionally, the device is durable and reliable, making it a great choice for long-term projects. The self-heating element also ensures that the thermistor remains accurate over a wide range of temperatures.
