The LM95235CIMM/NOPB is a 11-bit Digital Temperature Sensor with a 2-wire SMBus interface that can monitor temperature. The LM95235 can be used to very accurately monitor the temperature of external devices such as microprocessors, graphics processors or a diode-connected MMBT3904 transistor. The LM95235 T_CRIT and OS Management outputs are asserted when either unmasked channel shutdown the system, to turn on the system fans or as a microcontroller interrupt function. The current Electronics 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 LM95235 has a programmable digital filter. The LM95235 contains a diode model selection bit to select between a typical Intel® processor on a 65 nm or 90 nm process or MMBT3904, as well as an offset register for maximum flexibility and best accuracy.
