MCP9600-E/MX Microchip

MCP9600 Thermocouple EMF to Temperature Converter, 1.5C 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 2 user-programmable configurations, such as alert - Supports Eight Devices per I C Bus polarity as either an active-low or active-high push-pull Operating Voltage Range: 2.7V to 5.5V output, and output function as a Comparator mode Operating Current: 300 A (typical) (useful for thermostat-type operation) or Interrupt mode Shutdown Current: 2 A (typical) for microprocessor-based systems. In addition, the Package: 20-lead MQFN alerts 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.
