perature exceeds a user-programmed setpoint. Hysteresis

is also programmable. The INT/CMPTR output is program-

mable as either a simple comparator for thermostat opera-

tion 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 setpoint

and hysteresis, and configuring the device.

The TCN75 powers up in Comparator Mode with a

default setpoint of 80°C with 5°C hysteresis. Defaults allow

independent operation as a stand-alone thermostat. A shut-

down command may be sent via the 2-wire bus to activate

the low-power standby mode. Address selection inputs

allow up to eight TCN75's to share the same 2-wire bus for

multi-zone 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.
