LM95213
2-Diode Input and Local Digital Temperature Sensor with
Two-Wire Interface and TCRIT Outputs
General Description
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 tem-
perature. The LM95213 can be used to very accurately mon-
itor 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 pro-
grammable limit and can be used to shutdown the system, to
turn on the system fans or as a microcontroller interrupt func-
tion. The current status of the TCRIT1, TCRIT2 and TCRIT3
pins can be read back from the status registers. Mask regis-
ters are available for further control of the TCRIT outputs.
LM95213's remote temperature channels have pro-
grammable 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: pro-
grammable conversion rate, shutdown mode, and turn off of
unused channels.
