MCP9800/1/2/3  
2-Wire High-Accuracy Temperature Sensor  
Features  
Description  
• Temperature-to-Digital Converter  
• Accuracy with 12-bit Resolution:  
- ±0.5°C (typ.) at +25°C  
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 (max.) from -10°C to  
+85°C.  
- ±1°C (max.) from -10°C to +85°C  
- ±2°C (max.) from -10°C to +125°C  
- ±3°C (max.) 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 (typ.)  
• Shutdown Current: 1 µA (max.)  
The MCP9800/1/2/3 family comes with user-program-  
mable 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  
the 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 fea-  
tures make the MCP9800/1/2/3 ideal for sophisticated  
multi-zone temperature-monitoring applications.  
• Office Equipment  
• Data Communication Equipment  
• Mobile Phones
