Package Type

General Description:

The TCN75 is a serially programmable temperature

sensor that notifies the host controller when ambient

temperature exceeds a user programmed set point.

Hysteresis is also programmable. The INT/CMPTR

output is programmable as either a simple comparator

for thermostat operation or as a temperature event

interrupt.

Communication

with

the

TCN75

is

accomplished via a two-wire bus that is compatible with

industry standard protocols. This permits reading the

current temperature, programming the set point and

hysteresis, and configuring the device.

The TCN75 powers up in Comparator mode with a

default set point of 80°C with 5°C hysteresis. Defaults

allow

independent

operation

as

a

stand-alone

thermostat. A shutdown command may be sent via the

2-wire bus to activate the low-power Standby mode.

Address selection inputs allow up to eight TCN75s to

share the same 2-wire bus for multizone monitoring.

All registers can be read by the host and the INT/

CMPTR output’s polarity is user programmable. Both

polled

and

interrupt

driven

systems

are

easily

accommodated. Small physical size, low installed cost,

and ease-of-use make the TCN75 an ideal choice for

implementing

sophisticated

system

management

schemes.
