LM96080
August 11, 2010
System Hardware Monitor with 2-Wire Serial Interface
General Description
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.
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.
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
≤ T
A ≤ +125°C. The LM96080 is available
in a 24-pin TSSOP package.
