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 (max.) from -10°C to
+85°C.
The MCP9800/1/2/3 family comes with user-program-
mable 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
the 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, I2C/
SMBus compatible serial interface, allowing up to eight
devices to be controlled in a single serial bus. These fea-
tures make the MCP9800/1/2/3 ideal for sophisticated
multi-zone temperature-monitoring applications.
