The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications. The registers allow user-selectable settings such as Shutdown or low-power modes and the specification of temperature Event and Critical output boundaries. When the temperature changes beyond the specified boundary limits, the MCP9808 outputs an Event signal. The user has the option of setting the event 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. The event output can also be configured as a Critical temperature output. This sensor has an industry-standard 2-wire, SMBus and Standard I2C compatible (100 kHz/400 kHz bus clock) serial interface, allowing up to eight sensors to be controlled in a single serial bus. These features make the MCP9808 ideal for sophisticated multi-zone temperature-monitoring applications.

MCP990x Family


The MCP9902/3/4 is a high-accuracy, low-cost, System Management Bus (SMBus) temperature sensor. The MCP9902/3/4 monitors up to four temperature channels. Advanced features such as Resistance Error Correction (REC), Beta Compensation, and automatic diode-type detection combine to provide a robust solution for complex environmental monitoring applications.

Resistance Error Correction automatically eliminates the temperature error caused by series resistance, allowing greater flexibility in routing thermal diodes. Beta Compensation eliminates temperature errors caused by low, variable beta transistors common in today's fine geometry processors. The automatic beta detection feature monitors the external diode/transistor and determines the optimum sensor settings for accurate temperature measurements regardless of processor technology. This frees the user from providing unique sensor configurations for each temperature monitoring application. These advanced features plus ±1°C measurement accuracy for both external and internal diode temperatures provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.

The MCP9600 is a fully integrated thermocouple Electromotive Force (EMF) to degree Celsius converter, with integrated Cold-Junction compensation. The MCP9600 supports eight thermocouple types (K, J, T, N, S, E, B, and R). The MCP9600 provides user-programmable registers, adding design flexibility for various temperature sensing applications. The registers allow user-selectable settings, such as low-power modes for battery-powered applications, an adjustable digital filter for fast transient temperatures, and four individually programmable temperature alert outputs, which can be used to detect multiple temperature zones.
