DESCRIPTION
●The bq24160, bq24160A, bq24161, bq24161B, bq24163, and bq24168 are highly integrated single cell Li-Ion battery charger and system power path management devices targeted for space-limited, portable applications with high capacity batteries. The single cell charger has dual inputs which allow operation from either a USB port or higher-power input supply (that is, AC adapter or wireless charging input) for a versatile solution. The two inputs are fully isolated from each other and are easily selectable using the I2C interface.
