Product details

2.5 A programmable charger for single-cell Li-ion packs

The Texas Instruments BQ24168YFFR is a single-cell Lithium Ion/Polymer battery charger with a programmable constant-current charge up to 2.5 A max. It uses an I²C interface for setting charge parameters and reading status, which makes it a good fit for designs that need to adjust the charge profile in firmware rather than with fixed resistors. The part is rated for a 3.7 V battery pack voltage and operates from a supply up to 6 V. Fault protection includes over-temperature and over-voltage shutdowns.

I²C control and charge current flexibility

The I²C interface lets you program the charge current, termination current, and voltage thresholds on the fly. This is useful when the same PCB must support different battery capacities or chemistries across product variants — no resistor swap, just a firmware change. The 2.5 A max charge current suits a single-cell Li-Ion/Polymer battery in a portable device.

Frequently asked questions

What is the charge current range for BQ24168YFFR?

The charge current is constant and programmable via I²C, with a maximum of 2.5 A. The lower end of the range is set by the I²C register limits — refer to the datasheet for the full programmable range.

What is the difference between BQ24168YFFR and BQ24168YFCR?

Functionally they are identical.
