MCP9844
В±1В°C Accurate, 1.8V Digital Temperature Sensor
Features: Description:
2 1MHz, 2-Wire I Cв„ў Interface User-Selectable Measurement Resolution:
-+0.5В°C, +0.25В°C, +0.125В°C, +0.0625В°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 -40В°C
to +125В°C to a digital word. It provides an accuracy of
В±0.2В°C/В±1В°C (typical/maximum) from +75В°C to +95В°C
with an operating voltage of 1.7V to 3.6V. Temperature Sensor Features: Temperature-to-Digital Converter (В°C) Sensor Accuracy:
-В±0.2В°C/В±1В°C (typ./max.) п‚® +75В°C to +95В°C
-В±0.5В°C/В±2В°C (typ./max.) п‚® +40В°C to +125В°C
-В±1В°C/В±3В°C (typ./max.) п‚® -40В°C to +125В°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 …
