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.

■ Operates from – 55°C to +125°C

■ Operating Range..................................... 2.7V - 5.5V

■ Programmable Trip Point and Hysteresis with

Power-up Defaults

■ Standard 2-Wire Serial Interface

■ Thermal Event Alarm Output Functions as

Interrupt or Comparator / Thermostat Output

■ Up to 8 TCN75's May Share the Same Bus

■ Shutdown Mode for Low Standby Power

Consumption

■ Low Power......................... 250µA (Typ.) Operating

1µA (Typ.) Shutdown Mode

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.

■ 8-Pin Plastic DIP, SOIC, and MSOP Packaging

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.
