Description

The MAX77818 integrates a high-performance 3A switchingcharger 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-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 with I2C interface.ApplicationsBluetooth HeadsetsHandheld DevicesIndustrial PCsInternet of Things (IoT)Portable Medical DevicesSmart Home Automation, SensorsWearable, Smart WatchesWireless Speakers
