MCP9804

±0.25°C Typical Accuracy Digital Temperature Sensor

Features

General 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

- +0.05°C (typical) lifetime drift

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 anAlert 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 a

temperature Alert interrupt output for microprocessor-

based systems. The Alert output can also be configured

as a critical temperature output only.

- ±0.0625°C or ±1 LSb (typical) repeatability

• User-Selectable Measurement Resolution:

- +0.5°C, +0.25°C, +0.125°C, +0.0625°C

• User-Programmable Temperature Limits:

- Temperature Window Limit

- 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

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

sophisticated, multi-zone, temperature-monitoring

applications.
