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 60C 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.
