TMP108 is a digital-output temperature sensor with a dynamically-programmable limit window, and under- and overtemperature alert functions. These features provide optimized temperature control without the need of frequent temperature readings by the controller or application processor.

The TMP108 features SMBus and two-wire interface compatibility, and allows up to four devices on one bus with the SMBus alert function.

The TMP108 is designed for thermal management optimization in a variety of consumer, computer, and environmental applications. The device is specified over a temperature range of –40°C to +125°C.
