Power Saving One-Shot Temperature Conversion Measurement
Space Saving SOT-23 Package
AEC-Q100 Qualified Grade 1
The MCP9800 is a digital temperature sensor capable of reading temperatures from -55°C to +125°C. Temperature data is measured from an integrated temperature sensor and converted to digital word with a user selectable 9 to 12-bit Sigma Delta Analog to Digital Converter.
The MCP9800 notifies the host controller when the ambient temperature exceeds a user programmed set point. The ALERT output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Communication with the sensor is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis and configuring the device.
Small physical size, low installed cost and ease of use
make the MCP9800 an ideal choice for implementing
sophisticated temperature system management schemes in a variety of applications.
Thermo 7 click is a Click board™ equipped with the sensor IC, which can digitize temperature measurements between -55°C and +125°C so that the temperature measurement data can be processed by the host MCU. Thermo 7 click provides an accuracy of ±1°C in the range from -10°C to +85°C. The sensor used on this Click board™ has a great combination of features that make it a perfect choice for any temperature measurement application: low power consumption, selectable sampling resolution, programmable interrupt engine, compact sensor size, alert output pin, and more. The sensor itself requires almost no external components, which simplifies the design, reducing the cost and cutting the time to market.
