Description
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.

The TC and Tsummation is implemented in milli-volt (mV) domain. The result, TH (mV), is converted to Degree
Celsius using the NIST ITS-90 Conversion database.
The T_ACY temperature accuracy specification is defined as the device accuracy to the NIST ITS-90
Thermocouple EMF to Degree Celsius Conversion Database. Tis also defined as the temperature differ-
ence between the hot and cold-junctions or temperatures from the NIST ITS-90 database with TC = 0°C.
The device measures temperature below the specified range, however, the sensitivity to changes in temperature
reduces exponentially. Type R and S measure down to -50°C, or -0.226 mVEMF and -0.235 mVEMF, respectively.
Type B measures down to 500°C or 1.242 mVEMF (see Figures 2-7, 2-8, 2-10, 2-11, 2-14 and 2-17).
Exceeding the VIN_CM input range may cause leakage current through the ESD protection diodes at the
thermocouple input pins. This parameter is characterized but not production tested.
