LM87 - Serial Interface System Hardware Monitor

Datasheet Summary

Description

The LM87 is a highly integrated data acquisition system for hardware monitoring of servers, Personal Computers, or virtually any microprocessor-based system.

In a PC, the LM87 can be used to monitor power supply voltages, motherboard and processor temperatures, and fan speeds.

Features

  • 1.
  • 234 Remote diode temperature sensing (2 channels).
  • 8 positive voltage inputs with scaling resistors for monitoring +5 V, +12 V, +3.3 V, +2.5 V, Vccp power supplies directly.
  • 2 inputs selectable for fan speed or voltage monitoring.
  • 8-bit DAC output for controlling fan speed.
  • Chassis Intrusion Detector input.
