Typical Application

Description:

Microchip Technology Inc.’s TCN75A digital tempera-

ture sensor converts temperatures between -40°C and

+125°C to a digital word, with ±1°C (typical) accuracy.

The TCN75A product comes with user-programmable

registers that provide flexibility for temperature-sensing

applications.

The

register

settings

allow

user-selectable, 0.5°C to 0.0625°C temperature

measurement

resolution,

configuration

of

the

power-saving

Shutdown

and

One-shot

(single

conversion on command while in Shutdown) modes

and the specification of both temperature alert output

and hysteresis limits. When the temperature changes

beyond the specified limits, the TCN75A outputs an

alert signal. The user has the option of setting the alert

output signal polarity as an active-low or active-high

comparator output for thermostat operation, or as

temperature

event

interrupt

output

for

microprocessor-based systems.

This sensor has an industry standard 2-wire, I2C™

compatible serial interface, allowing up to eight devices

to be controlled in a single serial bus. These features

make the TCN75A ideal for low-cost, sophisticated

multi-zone temperature-monitoring applications.
