The LM95213 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) interface that can monitor the temperature of two remote diodes as well as its own temperature. The LM95213 can be used to very accurately monitor the temperature of up to two external devices such as microprocessors, graphics processors or diode-connected 2N3904s.

The LM95213 reports temperature in two different formats for +127.875°C/–128°C range and 0°C/255°C range. The LM95213 TCRIT1, TCRIT2 and TCRIT3 outputs are triggered when any unmasked channel exceeds its corresponding programmable 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 TCRIT1, TCRIT2 and TCRIT3 pins can be read back from the status registers. Mask registers are available for further control of the TCRIT outputs.

The LM95213's remote temperature channels have programmable digital filters to minimize unwanted TCRIT events when temperature spikes are encountered.

For optimum flexibility and accuracy each LM95213 channel includes offset correction registers for targeting diodes other than the 2N3904. A three level address pin allows connection of up to 3 LM95213s to the same SMBus master. The LM95213 includes power saving functions such as: programmable conversion rate, shutdown mode, and turn off of unused channels.
