Description

General part information

LM95234 Series

LM95234 is an 11-bit digital temperature sensor with a 2-wire System Management Bus (SMBus) interface that can very accurately monitor the temperature of four remote diodes as well as its own temperature that includes patent pending remote diode TruTherm BJT beta compensation beta compensation technology. The four remote diodes can be external devices such as microprocessors, graphics processors or diode-connected 2N3904s. The LM95234's TruTherm BJT beta compensation technology allows sensing of 90 nm or 65 nm process thermal diodes accurately.

The LM95234 reports temperature in two different formats for +127.875°C/–128°C range and 0°C/255°C range. The LM95234TCRIT1,TCRIT2andTCRIT3outputs 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 theTCRIT1,TCRIT2andTCRIT3pins can be read back from the status registers. Mask registers are available for further control of theTCRIToutputs.

Two LM95234 remote temperature channels have programmable digital filters while the other two remote channels utilize a fault-queue to minimize unwantedTCRITevents when temperature spikes are encountered.
