3 Description
The LM95010 is a digital output temperature
sensor that has single-wire interface compatible with
the SensorPath interface. It uses a ΔVbe analog
temperature sensing technique that generates a
differential voltage that is proportional to temperature.
This voltage is digitized using a Sigma-Delta analogto-
digital converter. The LM95010 is part of a
hardware monitor system, comprised of two parts:
the PC System Health Controller (Master), such as
a Super I/O, and up to seven slaves of which four
can be LM95010s. Using SensorPath, the LM95010
will be controlled by the master and report to the
master its own die temperature. SensorPath data is
pulse width encoded, thereby allowing the LM95010
to be easily connected to many general purpose
micro-controllers.
