LM80 Datasheet (Texas Instruments) - Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor

LM80, Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor

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.
