MCP9800/1/2/3  
2-Wire High-Accuracy Temperature Sensor  
Features:  
Description:  
• Temperature-to-Digital Converter  
• Accuracy with 12-bit Resolution:  
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.  
- ±0.5°C (typical) at +25°C  
- ±1°C (maximum) from -10°C to +85°C  
- ±2°C (maximum) from -10°C to +125°C  
- ±3°C (maximum) from -55°C to +125°C  
• User-selectable Resolution: 9–12 bit  
• Operating Voltage Range: 2.7V to 5.5V  
• 2-wire Interface: I2C™/SMBus Compatible  
• Operating Current: 200 µA (typical)  
• Shutdown Current: 1 µA (maximum)  
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.  
• Power-saving One-shot Temperature  
Measurement  
• Available Packages: SOT-23-5, MSOP-8, SOIC-8  
Typical Applications:  
• Personal Computers and Servers  
• Hard Disk Drives and Other PC Peripherals  
• Entertainment 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  
• Office Equipment  
• Data Communication Equipment  
• Mobile Phones  
sophisticated  
applications.
