temperature sensor converts temperatures between
-40В°C and +125В°C to a digital word with В±0.25В°C/В±1В°C
(typical/maximum) accuracy.
The MCP9804 comes with user-programmable registers
that provide flexibility to temperature sensing
applications. The registers allow user-selectable
settings such as Shutdown or Low-Power modes and
the specification of temperature Alert window limits and
critical output limits. When the temperature changes
beyond the specified boundary limits, the MCP9804
outputs an Alert signal. The user has the option of setting
the Alert output signal polarity as an active-low or activehigh comparator output for thermostat operation, or as a
temperature Alert interrupt output for microprocessorbased systems. The Alert output can also be configured …
