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 I 2C ™ 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. The 10 mV LSB and 2.56 volt input range is ideal for accepting inputs from a linear sensor such as the LM50. The ^BTI is used as an input from either digital or thermostat sensors such as LM75 and LM56
