LM95233 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 LM95233 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 LM95233's TruTherm BJT beta compensation technology allows sensing of 90nm or 65nm process thermal diodes accurately.
The LM95233 reports temperature in two different formats for +127.875°C/–128°C range and 0°C/255°C range. The LM95233 ^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
