MCP9804

±0.25°C Typ. Accuracy Digital Temperature Sensor

Features

Description

• Accuracy:

Microchip Technology Inc.’s MCP9804 digital

temperature sensor converts temperatures between

-40°C and +125°C to a digital word with ±0.25°C/±1°C

(typical/maximum) accuracy.

- ±0.25°C (typical) from -40°C to +125°C

- ±1°C (maximum) from -40°C to +125°C

• User Selectable Measurement Resolution:

- 0.5°C, 0.25°C, 0.125°C, 0.0625°C

• User Programmable Temperature Limits:

- Temperature Window Limit

The MCP9804 comes with user-programmable

registers that provide flexibility 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 active-high comparator output for thermostat

operation, or as temperature Alert interrupt output for

microprocessor-based systems. The Alert output can

also be configured as a Critical temperature output

only.

- Critical Temperature Limit

• User Programmable Temperature Alert Output

• Operating Voltage Range: 2.7V to 5.5V

• Operating Current: 200 µA (typical)

• Shutdown Current: 0.1 µA (typical)

• 2-wire Interface: I²C/SMBus Compatible

• Available Packages: 2x3 DFN-8, MSOP-8

Typical Applications

This sensor has an industry standard 100 kHz 2-wire,

SMBus/I²C compatible serial interface, allowing up to

eight or sixteen sensors to be controlled with a single

serial bus (see Table 3-2 for available Address codes).

These features make the MCP9804 ideal for

• General Purpose

• Industrial Applications

• Industrial Freezers and Refrigerations

• Food Processing
