Temperature sensors are widely used in almost any kind of environment, such as industrial, commercial, and residential. The MCP9701AT-E/TT provides an accurate, low cost analog and digital output type temperature sensor for measuring temperature. The MCP9701AT-E/TT works on the principle of thermal conductivity, making it reliable and accurate for use in a variety of temperatures.

The MCP9701AT-E/TT consists of an integrated PTC thermistor mounted on an 8-pin SOIC package. The thermistor itself is made up of NTC chips which have temperature coefficients of resistance that can be used to measure temperature changes. A small current is applied to the thermistor which causes the impedance of the thermistor to vary with temperature. The temperature is then fed into a voltage-to-temperature converter, usually an analog- to-digital converter, which is then used to convert the temperature to an analog or digital reading.

The MCP9701AT-E/TT provides a temperature-sensing range of -40°C to +125°C (-40°F to +257°F). The operating voltage of the MCP9701AT-E/TT is from 4V to 5.25V and the quiescent current is typically 700nA. The MCP9701AT-E/TT has a built-in temperature offset option which allows it to automatically adjust its offset temperature point. It also includes a temperature hysteresis which helps to prevent temperatures from fluctuating too quickly.

The MCP9701AT-E/TT offers a variety of output options including a 5V, 10mV/°C analog output, 1V/°C scaling voltage output, and a 12-bit digital output. The digital output consists of a one-wire serial interface that can communicate with any microcontroller or host microprocessor through a 2-Wire, 3-Wire, or SPI bus. The digital output supports both the I2C and 1-wire temperature protocol, making it compatible with a wide variety of microcontrollers and processors. Additionally, the MCP9701AT-E/TT has an internal watchdog timer which prevents detection of incorrect temperatures.

The MCP9701AT-E/TT is suitable for a many temperature sensing applications such as controlling heavy duty INDUSTRIAL machines, HVAC systems, electric vehicles, and battery management systems. It finds common usage in residential, commercial, automotive, and industrial applications. The MCP9701AT-E/TT is a great choice for users looking for accurate temperature measurements.
