LM96011

Hardware Monitor with Thermal Diode Input and

™

SensorPath Bus

— Internal local temperature zone

— 0.5 ˚C resolution

— Measures temperatures up to 140 ˚C

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-

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 140˚C and down to -55˚C. Using Σ∆ ADC it

measures Vccp, +2.5V, +3.3V, +5V and +12V analog input

voltages with internal scaling resistors.
