资 源 简 介

The LM95245 is an 11-bit digital temperature sensor with a2-wire System Management Bus (SMBus) interface andTruTherm technology that can monitor the temperature of aremote diode as well as its own temperature. The LM95245can be used to very accurately monitor the temperature ofexternal devices such as microprocessors. TruTherm technologyallows the LM95245 to precisely monitor thermaldiodes found in 90 nm and smaller geometry processes. TheLM95245 is specifically targeted for Intel processors on 45nmprocess. LM95245 reports temperature in two different formatsfor +127.875°C/-128°C range and 0°C/255°C range.The LM95245 T_CRIT and OS outputs are asserted wheneither unmasked channel exceeds its programmed limit andcan be used to shutdown the system, to turn on the systemfans, or as a microcontroller interrupt funcTIon. The currentstatus of the T_CRIT and OS pins can be read back from thestatus registers via the SMBus interface. All limits have ashared programmable hysteresis register.
