The Microchip Technology Inc. MCP960X/L0X/RL0X converts thermocouple EMF to degree Celsius with integrated cold-junction compensation. The temperature correction coefficients are derived from the National Institute of Standards and Technology (NIST) ITS-90 Thermocouple Database. The MCP9600/01 corrects the thermocouple nonlinear error characteristics of eight thermocouple types and outputs ±0.5°C/±1.5°C (Typ./Max.). The MCP960X/L0X/RL0X digital temperature sensor comes with user-programmable registers which provide design flexibility for various temperature sensing applications. The registers allow user-selectable settings, such as Low-Power modes for battery powered applications, adjustable digital filter for fast transient temperatures and four individually programmable temperature alert outputs which can be used to detect multiple temperature zones. In addition, the MCP9601/L01/RL01 family provides integrated Thermocouple open-circuit and short-circuit detection features. An alert signal is asserted when the thermocouple wire is broken or disconnected. Similarly, alert signal is asserted when the Thermocouple is shorted to ground or power. The temperature alert limits have multiple user-programmable configurations, such as alert polarity as either an active-low or active-high push-pull output, and output function as a Comparator mode (useful for thermostat-type operation) or Interrupt mode
for microprocessor-based systems. In addition, the alerts can detect either a rising or a falling temperature with up to +255°C hysteresis. This sensor uses an industry standard 2-wire, I2C compatible serial interface and supports up to eight devices per bus by setting the device address using the ADDR pin.
