LM95213 is an 11-bit 2-wire System Management Bus (SMBus) interface digital temperature sensor that monitors the temperature of two remote diodes as well as their own temperature. LM95213 can be used to monitor temperatures up to two external devices such as microprocessors, graphics processors, or connected into the 2N3904 series of diodes very accurately.
LM95213 reported temperatures in the 127.875°C/-128°C temperature range and 0°C/255°C in two different formats. LM95213^TCRIT1,^TCRIT2^TCRIT3 outputs trigger any east-window event channel when it exceeds its corresponding programmable limit and can be used to shut down the system, steer the system fan, or as an interrupt function for the microcontroller. The status of the ^TCRIT1,^ TCRIT2 and ^ TCRIT3 pins can read state registers. Shielded registers can be used to further control the ^ TCRIT output.
LM95213 remote temperature channel programmable digital filter to minimize unnecessary^TCRIT events when temperature spikes are encountered.
For optimal flexibility and accuracy, include a 2N3904 diode with a 2N3904 diode for each LM95213 channel offset correction register. A 3-level address pin allows up to 3 LM95213s to be connected to the same SMBus master. LM95213 include power-saving features such as programmable slew rate, shutdown mode, and shutdown of unused channels.
