The FAN54120 is a USB-compatible single-cell, linear Li-Ion battery charger with "Power Back" Capability, It supports dead battery revival, pre-charge, fast charge, and float charge states.
Fast charging current (IFAST) is set with an external resistor. Pre-charge (IPRE) and charge complete (ICHGEND) currents are factory set at IFAST/5.2 and IFAST/10, respectively.
An open-drain ("STAT" ) pin provides charge and/or fault status indication. The "Power Back" enables to power accessories from the battery
