EVALUATION KIT AVAILABLE MAX77818 Dual Input, Power Path, 3A Switch Mode Charger with Fuel Gauge General Description The MAX77818 integrates a high-performance 3A switching charger and proprietary ModelGauge™ m5 fuel gauge in a space saving WLP package, ideal for USB powered portable devices. The smart power path charger supports two inputs with reverse blocking and USB On-theGo (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 shortterm accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industryleading fuel-gauge accuracy. The device also integrates two high voltage input LDOs and is highly programmable with I2C interface.
