3 Description
TMP108 is a digital-output temperature sensor with a
dynamically-programmable limit window, and underand
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.
