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.
Key Features
