Why Do Applications Need
a Temperature Sensor?
As today’s electronic systems run faster and as silicon content increases, these
applications are generating more heat than ever, making the need to monitor
temperature increasingly important. A temperature sensor can effectively measure
the system and processor temperatures and allows the processor and system bus
frequencies to be throttled back when the temperature exceeds a preset limit.
This ensures product safety and reliability while minimizing the need for cooling fans
and heat sinks which may not be practical in today’s increasingly compact designs.
For systems that do include a fan to maintain proper conditions, temperature sensors
can be used to vary the fan speed as needed to reduce noise, reduce power
consumption, and prolong the life of the fan.
In portable applications that utilize Li-ion or Li-polymer batteries, temperatures in
excess of 60°C can cause the batteries to overheat and swell, catch on fire, or even
explode. A temperature sensor can actively monitor the battery temperature, allowing
the system to warn the user, to shut itself down, or to even shut down the battery
charging in the event of an over-temperature situation, thereby increasing the safety
and reliability of the application.

Atmel Digital Temperature Sensors
Accurate, Complete, and Easy to Use
Atmel Digital Temperature Sensor products are complete and easy-to-use solutions that address the ever-growing need
for temperature sensing. Atmel offers these solutions as drop-in replacements for industry-standard LM75-type devices
as well as JEDEC-standard compliant solutions for DDR3 and DDR4 DIMM modules. Atmel Digital Temperature Sensors also
provide enhanced features, such as integrated EEPROM and nonvolatile registers, to reduce BOM cost, improve system
flexibility and product reliability, and enhance application safety.
In terms of performance, Digital Temperature Sensors offer excellent accuracy and a precise, fully calibrated digital temp­
erature reading in degrees celsius. Digital Temperature Sensors eliminate the need for additional components, such as an
A/D converter, within the application, and there is no need to calibrate components or the system at specific reference
temperatures as required when using thermistors. Atmel Digital Temperature Sensors take care of it all, enabling the critical
system temperature monitoring function to be simplified.
