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 I
2
C
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 pro-
vided 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.
The LM80’s 2.8V to 5.75V supply voltage range, low supply
current, and I
2
C interface make it ideal for a wide range of
applications. These include hardware monitoring and protec-
tion applications in personal computers, electronic test
equipment, and office electronics.
