Description

General 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. Actual values for these inputs can be read at any time. Programmable WATCHDOG limits in the LM87 activate a fully programmable and maskable interrupt system with two outputs (INT# and THERM#).

Features
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
WATCHDOG comparison of all monitored values
SMBus or I2C Serial Bus interface compatibility
VID0-VID4 or IRQ0-IRQ4 monitoring inputs
On chip temperature sensor
