Typical Application

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, I2C™/

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.
