Description:
Microchip Technology Inc.’s MCP9800/1/2/3 family of
digital temperature sensors converts temperatures
between -55°C and +125°C to a digital word. They
provide an accuracy of ±1°C (maximum) from -10°C to
+85°C.
The
MCP9800/1/2/3
family
comes
with
user-programmable registers that provide flexibility for
temperature sensing applications. The register settings
allow user-selectable 9-bit to 12-bit temperature
measurement resolution, configuration of the
power-saving Shutdown and One-shot (single
conversion on command while in Shutdown) modes
and the specification of both temperature alert output
and hysteresis limits. When the temperature changes
beyond the specified limits, the MCP9800/1/2/3 outputs
an alert signal. The user has the option of setting the
alert output signal polarity as an active-low or
active-high comparator output for thermostat operation,
or as temperature event interrupt output for
microprocessor-based systems.
This sensor has an industry standard 2-wire, I
2
C™/
SMBus compatible serial interface, allowing up to eight
devices to be controlled in a single serial bus. These
features make the MCP9800/1/2/3 ideal for
sophisticated
multi-zone
temperature-monitoring
applications.
Typical Applications:
Personal Computers and Servers
Hard Disk Drives and Other PC Peripherals
Entertainment Systems
Office Equipment
Data Communication Equipment
Mobile Phones
