LM80  
Serial Interface ACPI-Compatible Microprocessor System  
Hardware Monitor  
n WATCHDOG comparison of all monitored values  
n Separate input to show status in Interrupt Status  
Register of additional external temperature sensors such  
as the LM56 or LM75  
n I2C Serial Bus interface compatibility  
n Shutdown mode to minimize power consumption  
n Programmable RST_OUT/OS pin: RST_OUT provides a  
Reset output; OS provides an Interrupt Output activated  
by an Overtemperature Shutdown event  
General Description  
The LM80 provides 7 positive voltage inputs, temperature  
measurement, fan speed measurement, and hardware  
2
™
monitoring on an I 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 I2C 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.
