LM95010
Digital Temperature Sensor with SensorPath™Bus in
MSOP8 Package
General Description
The LM95010 is part of a hardware monitor system, com-
prised of two parts the PC System Health Controller (Master)
and one or more LM95010s (Slave). Using the SensorPath™
single-wire bus, the LM95010 will be controlled by the Mas-
ter and report to the master temperature of its own die, most
likely the printed circuit board temperature.
