LM96011
Hardware Monitor with Thermal Diode Input and
SensorPath
Bus
General Description
The LM96011 is part of a hardware monitor system, com-
prised of two parts the Super I/O (Master) and LM96011
(slave). The LM96011 will be controlled by the Master and
report to the master temperature, and voltage measure-
ments using a SensorPath
single-wire bus. The LM96011
measures the temperature of its own die as well as an
external device such as a processor thermal diode or a diode
connected transistor. The LM96011 can resolve tempera-
tures up to 140C and down to -55C. Using
Σ
ADC it
measures Vccp, +2.5V, +3.3V, +5V and +12V analog input
voltages with internal scaling resistors.
