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

Thermocouple

temperature converter 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 two-wire, I2C

compatible serial interface and supports up to eight

devices per bus by setting the device address using the

ADDR pin.
