Hot-selling and scarce LM95213CISD/NOPB 2-Diode Input and Local Digital Temperature Sensor 14WSON spot stock

Product Descriptions

The LM95213 is an 11-bit digital temperature sensorwith  a  2-wire  System  Management  Bus  (SMBus)interface  that  can  monitor  the  temperature  of  tworemote diodes as well as its own temperature . TheLM95213 can be used to very accurately monitor thetemperature of up to two external devices such asmicroprocessors,   graphics   processors   or   diodeconnected 2N3904s 

The  LM95213  reports  temperature  in  two  differentformats for +127.875°C/–128°C range and 0°C/255°Crange . The LM95213 TCRIT1, TCRIT2 and TCRIT3outputs  are triggered when  any  unmasked  channelexceeds  its  corresponding  programmable  limit  andcan be used to shutdown the system, to turn on thesystem fans or as a microcontroller interrupt function .The  current  status  of  the  TCRIT1,  TCRIT2  andTCRIT3  pins  can  be  read  back  from  the  statusregisters .  Mask  registers  are  available  for  furthercontrol of the TCRIT outputs .

The  LM95213's  remote  temperature  channels  haveprogrammable  digital  filters  to  minimize  unwantedTCRIT    events    when    temperature    spikes    areencountered 

For optimum flexibility and accuracy each LM95213channel   includes   offset   correction   registers   fortargeting diodes other than the 2N3904 . A three leveladdress pin allows connection of up to 3 LM95213sto the same SMBus master . The LM95213 includespower   saving   functions   such   as:   programmableconversion  rate,  shutdown  mode,  and  turn  off  ofunused channels .
