LM96080  
System Hardware Monitor with 2-Wire Serial Interface  
General Description  
Features  
LM96080, compatible to LM80, is a hardware monitor that  
contains a 10-bit delta-sigma ADC capable of measuring 7  
positive voltages and local temperature. The LM96080 also  
measures the speed of two fans and includes other hardware  
monitoring on an I2C® interface. The LM96080 includes a se-  
quencer that performs WATCHDOG window comparisons of  
all measured values and its interrupt outputs become active  
when any values exceed the programmed limits.

7 Positive Voltage Inputs with 10-bit Resolution  
2 Programmable Fan Speed Monitoring Inputs  
2.5 mV LSb and 2.56V Input Range  
Chassis Intrusion Detector Input  
WATCHDOG Comparison of All Monitored Values  
Separate Input to Show Status in Interrupt Status Register  
of Additional External Temperature Sensors Such as the  
LM26/27, LM56/57, LM73, or LM75  
The LM96080 is especially suited to interface to both linear  
and digital temperature sensors. The 2.5 mV LSb (least sig-  
nificant bit) and 2.56 volt input range is ideal for accepting  
inputs from a linear sensor such as the LM94022. The BTI is  
used as an input from either digital or thermostat sensors such  
as LM73, LM75, LM56, LM57, LM26, LM27, LM26LV, or other  
LM96080.  
I2C Serial Bus Interface Compatibility, Supports Standard  
Mode, 100 kbits/s, and Fast Mode, 400 kbits/s  
■
Shutdown Mode to Minimize Power Consumption  
■
■
Programmable RST_OUT/OS Pin: RST_OUT Provides a  
Reset Output; OS Provides an Interrupt Output Activated  
by an Overtemperature Shutdown Event  
The LM96080 supports Standard Mode (Sm, 100 kbits/s) and  
Fast Mode (Fm, 400 kbits/s) I2C interface modes of operation.  
LM96080 includes an analog filter on the I2C digital control  
lines that allows improved noise immunity and supports  
TIMEOUT reset function on SDA and SCL that prevents I2C  
bus lockup. Three I2C device address pins allow up to 8 parts  
on a single bus.

The LM96080's 3.0V to 5.5V supply voltage range, low supply  
current, and I2C interface make it ideal for a wide range of  
applications. Operation is guaranteed over the temperature  
range of (−40)°C ≤ TA ≤ +125°C. The LM96080 is available  
in a 24-pin TSSOP package.
