MCP9600 Thermocouple EMF to Temperature Converter, 1.5 C Maximum Accuracy Features Description Thermocouple Electromotive Force (EMF) to C Microchip Technology Inc.s MCP9600 converts Converter thermocouple EMF to degree Celsius with integrated Cold-Junction compensation. This device corrects the - Integrated Cold-Junction Compensation thermocouple nonlinear error characteristics of eight Supported Types (designated by NIST ITS-90): thermocouple types and outputs 1.5C accurate - Type K, J, T, N, S, E, B and R temperature data for the selected thermocouple. The 1.5C (Max.) Hot-Junction Accuracy correction coefficients are derived from the National Measurement Resolution: Institute of Standards and Technology (NIST) ITS-90 Thermocouple Database. - Hot- and Cold-Junctions: 0.0625C (typical) Four Programmable Temperature Alert Outputs The MCP9600 digital temperature sensor comes with user-programmable registers which provide design - Monitor Hot- or Cold-Junction temperatures flexibility for various temperature sensing applications. - Detect rising or falling temperatures The registers allow user-selectable settings such as - Up to 255C of Programmable Hysteresis Low-Power modes for battery-powered applications, Programmable Digital Filter for Temperature adjustable digital filter for fast transient temperatures Low Power: and four individually programmable temperature alert - Shutdown Mode outputs which can be used to detect multiple temperature zones. - Burst Mode: 1 to 128 Temperature Samples 2 2-wire Interface: I C Compatible, 100 kHz The temperature alert limits have multiple user 2 programmable configurations such as alert polarity as - supports eight devices per I C bus either an active-low or active-high push-pull output, and Operating Voltage Range: 2.7V to 5.5V output function as comparator mode (useful for Operating Current: 300 A (typical) thermostat-type operation) or interrupt mode for Shutdown Current: 2 A (typical) microprocessor-based systems. In addition, the alerts Package: 20-lead MQFN can detect either a rising or a falling temperature with up to 255C hysteresis. 2 Typical Applications This sensor uses an industry standard 2-wire, I C compatible serial interface and supports up to eight Petrochemical Thermal Management devices per bus by setting the device address using the Hand-Held Measurement Equipment ADDR pin.
