MCP960X/L0X/RL0X Thermocouple EMF to Temperature Converter, 1.5C Maximum Accuracy Features Description Thermocouple Electromotive Force (EMF) to C The Microchip Technology Inc. MCP960X/L0X/RL0X Converter: converts thermocouple EMF to degree Celsius with integrated cold-junction compensation. The - Integrated cold-junction compensation temperature correction coefficients are derived from - Integrated thermocouple open-circuit and the National Institute of Standards and Technology short-circuit detection (NIST) ITS-90 Thermocouple Database. The Supported Types (designated by NIST ITS-90): MCP9600/01 corrects the thermocouple nonlinear - Type K, J, T, N, S, E, B and R error characteristics of eight thermocouple types and Sensor Accuracy for Thermocouple Hot-Junction: outputs 0.5C/1.5C (Typ./Max.). - MCP9600/01 0.5C/1.5C (typ./max.) The MCP960X/L0X/RL0X digital temperature sensor - MCP96L00/L01 2.0C/4.0C (typ./max.) comes with user-programmable registers which provide design flexibility for various temperature - MCP96RL00/RL01 4.0C/8.0C (typ./max.) sensing applications. The registers allow Measurement Resolution: user-selectable settings, such as Low-Power modes - Hot and cold-junctions: +0.0625C (typical) for battery powered applications, adjustable digital filter Four Programmable Temperature Alert Outputs: for fast transient temperatures and four individually - Monitor hot or cold-junction temperatures programmable temperature alert outputs which can be - Detect rising or falling temperatures used to detect multiple temperature zones. - Up to 255C of programmable hysteresis In addition, the MCP9601/L01/RL01 family provides Programmable Digital Filter for Temperature integrated Thermocouple open-circuit and short-circuit detection features. An alert signal is asserted when the Low Power: thermocouple wire is broken or disconnected. Similarly, - Shutdown mode alert signal is asserted when the Thermocouple is - Burst mode: 1 to 128 temperature samples shorted to ground or power. 2 2-Wire Interface: I C Compatible, 100 kHz: The temperature alert limits have multiple 2 - Supports eight devices per I C Bus user-programmable configurations, such as alert Operating Voltage Range: 2.7V to 5.5V polarity as either an active-low or active-high push-pull Operating Current: 300 A (typical) output, and output function as a Comparator mode (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. Typical Applications 2 This sensor uses an industry standard 2-wire, I C Petrochemical Thermal Management compatible serial interface and supports up to eight Hand-Held Measurement Equipment devices per bus by setting the device address using the Industrial Equipment Thermal Management ADDR pin.
