The LM95213 can be used to very accurately monitor the temperature of up to two external devices such as microprocessors, graphics processors or diodeconnected 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 unwant...
