The LM95245CIMM is an 11-bit digital temperature sensor with a 2-wire SMBus interface that can monitor the temperature of a remote diode as well as its own temperature. The LM95245 can be used to very accurately monitor the temperature of external devices such as microprocessors. The LM95245 is specifically targeted for Intel processors on 45nm process. The LM95245 T_CRIT and OS outputs are asserted when either unmasked channel exceeds its programmed limit and can be used to shutdown the system, to turn on the system fans or as a microcontroller interrupt function. The current status of the T_CRIT and OS pins can be read back from the status registers via the SMBus interface. All limits have a shared programmable hysteresis register. The remote temperature channel of the LM95245 has a programmable digital filter.
