3 Description
The LM95214 device 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. The four remote diodes can be
external devices such as microprocessors, graphics
processors that target the ideality of a 2N3904
transistor or diode-connected 2N3904s.
The LM95214 reports temperature in two different
formats for +127.875°C/–128°C range and 0°C/255°C
range. The LM95214 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.
Two LM95214 remote temperature channels have
programmable digital filters while the other two
remote channels use a fault-queue to minimize
unwanted TCRIT events when temperature spikes
are encountered.
For optimum flexibility and accuracy, each LM95214
channel includes registers for offset correction. A
three-level address pin allows connection of up to 3
LM95214s to the same SMBus master. The LM95214
includes power saving functions such as:
programmable conversion rate, shutdown mode, and
disabling of unused channels.
