LM90 Datasheet

Features and benefits

n Accurately senses die temperature of remote ICs or diode junctions n Offset register allows sensing a variety of thermal diodes accurately n On-board local temperature.

Application

n System Thermal Management (e.g. Laptop, Desktop, Workstations, Server) n Electronic Test Equipment n Office Electronic.

Description

The LM90 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) serial interface. The LM90 accurately measures its own temperature as well as the temperature of an external device, such as processor thermal diode or diode.
