LM80 Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor
General Description
The LM80 provides 7 positive voltage inputs, temperature measurement, fan speed measurement, and hardware monitoring on an I2C™ interface.
The LM80 performs WATCHDOG™ comparisons of all measured values and an open-drain interrupt output becomes 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.
The LM80 is especially suited to interface to both linear and digital temperature sensors.
