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.  
–
