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.
