Maxim MAX77818EWZ+T

锂离子/聚合物3A-40°C ~ 85°C（TA）

Overview

The MAX77818EWZ+ 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-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.
