    MCP9844
    ±1°C Accurate, 1.8V Digital Temperature Sensor
    Features: Description:
    2 1MHz, 2-Wire I C™ Interface User-Selectable Measurement Resolution:
    -+0.5°C, +0.25°C, +0.125°C, +0.0625°C User-Programmable Temperature Limits:
    -Temperature Window Limit
    -Critical Temperature Limit User-Programmable Temperature Alert Output Specified VDD Range: 1.7V to 3.6V Operating Current: 100 µA (typical) Available Package: 8-Pin TDFN Microchip Technology Inc.’s MCP9844 digital
    temperature sensor converts temperature from -40°C
    to +125°C to a digital word. It provides an accuracy of
    ±0.2°C/±1°C (typical/maximum) from +75°C to +95°C
    with an operating voltage of 1.7V to 3.6V. Temperature Sensor Features: Temperature-to-Digital Converter (°C) Sensor Accuracy:
    -±0.2°C/±1°C (typ./max.)  +75°C to +95°C
    -±0.5°C/±2°C (typ./max.)  +40°C to +125°C
    -±1°C/±3°C (typ./max.)  -40°C to +125°C Typical Applications: The MCP9844 digital temperature sensor comes with
    user-programmable registers that provide flexibility for
    temperature sensing applications. The registers allow
    user-selectable settings such as Shutdown or LowPower modes, and the specification of temperature
    event boundaries. When the temperature changes
    beyond the specified event boundary limits, the
    MCP9844 outputs an Alert signal at the Event pin. The
    user has the option of setting the temperature event
    output signal polarity as either an active-low or activehigh comparator output for the thermostat operation, or
    as a temperature event interrupt output for ...
