DESCRIPTION
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 ideal 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.
