MAX77818 Datasheet 3a Switch Mode Charger

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX77818 EVALUATION KIT AVAILABLE Dual Input, Power Path, 3A Switch Mode Charger with Fuel Gauge.

General Description

The MAX77818 integrates a high-performance 3Aswitching 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 ponents.

The ModelGauge m5 algorithm bines the excellent shortterm accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge, along with temperature pensation to provide industryleading fuel-gauge accuracy.
