LM80 Description
The LM80 provides 7 positive voltage inputs, temperature measurement, fan speed measurement, and hardware monitoring on an I2C interface. The LM80 performs WATCHDOG parisons of all measured values and an open-drain interrupt output bees active when any values exceed programmed limits. A Chassis Intrusion input is provided to monitor and reset an external circuit designed to latch a chassis intrusion event.
