DESCRIPTION

The bq24165, bq24166 and bq24167 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 (i.e., AC adapter or

wireless charging input) for a versatile solution. The two inputs are fully isolated from each other and are

managed by the bq24165/166/167 with the IN input

having precedence.
