3 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 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.
