LM87 Serial Interface System Hardware Monitor with Remote Diode Temperature Sensing April 2000 LM87 Serial Interface System Hardware Monitor with Remote Diode Temperature Sensing 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#).
