EVALUATION KIT AVAILABLE  
MAX77818  
Dual Input, Power Path,  
3A Switch Mode Charger with Fuel Gauge  
General Description  
Benefits and Features  
Smart Power Path, Dual Input Switching Charger  
• Up to 13.4V Operating/16V Withstand/4A (CHGIN)  
• Up to 6V Operating/1.26A (WCIN)  
TheMAX77818integratesahigh-performance3Aswitching  
charger and proprietary ModelGauge™ m5 fuel gauge  
in a space saving WLP package, ideal for USB powered  
portable devices. The smart power path charger sup-  
ports two inputs with reverse blocking and USB On-the-  
Go (OTG), integrates all power switches, operates at  
high-switching frequency with high efficiency, enabling  
low heat designs with small external components. The  
ModelGauge m5 algorithm combines the excellent short-  
term accuracy and linearity of a coulomb counter with  
the long-term stability of a voltage-based fuel gauge,  
along with temperature compensation to provide industry-  
leading fuel-gauge accuracy. The device also integrates  
two high voltage input LDOs and is highly programmable
