LM96010

Hardware Monitor with Dual Thermal Diodes and

SensorPath

General Description

The LM96010 is part of a hardware monitor system, com-

prised of two parts the Super I/O (Master) and LM96010

(slave). The LM96010 will be controlled by the Master and

report to the master temperature, and voltage measure-

ments using the SensorPath

LM96010 measures the temperature of its own die as well as

two external devices such as a processor thermal diode or a

diode connected transistor. The LM96010 can resolve tem-

peratures 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.
