General Description:

Applications:

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.

• Thermal Protection for High-Performance CPUs

• Solid-State Thermometer

• Fire/Heat Alarms

• Thermal Management in Electronic Systems:

- Computers

- Telecom Racks

- Power Supplies/UPS/Amplifiers

• Copiers/Office Electronics

• Consumer Electronics

The TCN75 powers up in Comparator mode with a

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

• Process Control

allow independent operation as

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.
