LM87 Overview
The LM87 is a highly integrated data acquisition system for hardware monitoring of servers, Personal puters, 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.
LM87 Key Features
- 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 directl
- 2 inputs selectable for fan speed or voltage monitoring
- 8-bit DAC output for controlling fan speed
- Chassis Intrusion Detector input
- WATCHDOG parison of all monitored
- SMBus™ or I2C Serial Bus interface
- VID0-VID4 or IRQ0-IRQ4 monitoring inputs
- On chip temperature sensor
LM87 Applications
- System Thermal and Hardware Monitoring for Servers, Workstations and PCs
