This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX77975/MAX77976 is a high-performance high-input 3.5/5.5A fast charger with Smart Power SelectorTM.

The IC can operate as a reverse boost without an additional inductor, allowing the battery to share its power through the charging port and is voltage programmable from 5V to 12V.

The device

Key Features

  • fully integrated low-loss power switches to provide small solution size and high-efficiency, even at high input voltage and high charging current. Its high switching frequency allows the use of a smaller sized inductor. The IC features true load disconnection in reverse boost mode and has an adjustable output current protection limit. The device is highly flexible and programmable through I2C configuration. The battery charger includes a Smart Power Selector to accommodate a wide range of batter.
