General Description

The LM96011 is part of a hardware monitor system, comprised 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 measurements 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 temperatures up to 140°C and down to -55°C. Using [Sigma][Delta] ADC it measures Vccp, +2.5V, +3.3V, +5V and +12V analog input voltages with internal scaling resistors.
