LM81 Datasheet Serial Interface ACpi-compatible Microprocessor System

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM81 Serial Interface ACPI-patible Microprocessor System Hardware Monitor June 1999 LM81 Serial Interface ACPI-patible Microprocessor System Hardware.

General Description

The LM81 is a highly integrated data acquisition system for hardware monitoring of servers, Personal puters, or virtually any microprocessor-based system.

In a PC, the LM81 can be used to monitor power supply voltages, temperatures, and fan speeds.

Actual values for these inputs can be read at any time.

Key Features

  • n Temperature sensing n 6 positive voltage inputs with scaling resistors for monitoring +5V, +12V, +3.3V, +2.5V, Vccp power supplies directly n 8-bit DAC output for controlling fan speed.
