3 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 a 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.

Dual Input, Integrated FET Charger for up to 2.5-A

Charging

–

20-V input rating, with Overvoltage Protection

(OVP)

–

6.5 V for USB Input up to 1.5 A

10.5 V for IN input (bq24160, bq24160A,

bq24161, bq24163) up to 2.5 A

–

6.5 V for IN input (bq24168) up to 2.5 A

•

Safe and Accurate Battery-Management

Functions

The power path management feature allows the

bq2416xx to power the system from a high-efficiency

independently charging the battery. The power-path

management architecture enables the system to run

with a defective or absent battery pack and enables

instant system turnon even with a totally discharged

battery or no battery.
