MAX77818EWZ+T Power Management ICs 3A Switch Mode Charger IC Lithium Ion Polymer Package 72-WLP
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.
Applications: ● Industrial PCs ● Portable Medical Devices ● Wearable, Smart Watches ● Handheld Devices ● Wireless Speakers ● Bluetooth Headsets ● Smart Home Automation, Sensors ● Internet of Things (IoT)
