Product details

2.5 A charge current for single-cell Li-Ion packs

The BQ24167YFFR is a single-cell Li-Ion battery charger IC from Texas Instruments with a programmable constant-current charge profile and a maximum charge current of 2.5 A. The USB interface simplifies the input power path for portable designs that draw from a USB port or adapter.

Protection and temperature grade

Built-in fault protection covers over-temperature and short-circuit conditions — essential for safe Li-ion charging in systems where the battery pack is not user-removable.

Package and footprint

The small footprint suits space-constrained portable and wearable designs, but the BGA layout requires careful PCB fan-out and a controlled solder-paste stencil for reliable assembly.

Frequently asked questions

Does BQ24167YFFR support fast charging?

The charge current is programmable up to 2.5 A maximum, which supports fast charging for single-cell Li-Ion packs that can accept that rate. The constant-current profile is set by the external resistor.

Can BQ24167YFFR charge a 4.2V Li-ion cell?

Yes. The battery pack voltage is specified as 3.7 V nominal, which corresponds to a 4.2 V full-charge termination voltage for standard Li-Ion cells. The charger regulates the termination voltage internally.
