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  
sophisticated  
applications.  
multi-zone  
temperature-monitoring  
• Personal Computers and Servers  
• PC Peripherals  
• Consumer Electronics
