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.

LIFE SUPPORT POLICY

NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT

DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL

COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION. As used herein:

1. Life support devices or systems are devices or

systems which, (a) are intended for surgical implant

into the body, or (b) support or sustain life, and

whose failure to perform when properly used in

accordance with instructions for use provided in the

labeling, can be reasonably expected to result in a

significant injury to the user.

2. A critical component is any component of a life

support device or system whose failure to perform

can be reasonably expected to cause the failure of

the life support device or system, or to affect its

safety or effectiveness.
