EVALUATION KIT AVAILABLE  
MAX34408/MAX34409  
SMBus Dual/Quad Current Monitor  
General Description  
The MAX34408 and MAX34409 are two- and four-channel  
Features  
●ꢀ Two/Four-ChannelꢀCurrentꢀMonitors  
●ꢀ Wideꢀ2.5Vꢀtoꢀ13.2VꢀCommon-ModeꢀRange  
●ꢀ Lowꢀ12.25mVꢀFull-ScaleꢀCurrent-SenseꢀVoltage  
current monitors that are configured and monitored with a  
2
standard I C/SMBus serial interface. Each unidirectional  
current sensor offers precision high-side operation with a  
low full-scale sense voltage. The devices automatically  
sequence through two or four channels and collect the  
current-sense samples and average them to reduce the  
effect of impulse noise. The raw ADC samples are com-  
pared to user-programmable digital thresholds to indicate  
overcurrent conditions. Overcurrent conditions trigger a  
hardware output to provide an immediate indication to  
shut down any necessary external circuitry.
