Product details

2-cell series charging with I²C control

The BQ25882YFFR: This is a multi-chemistry switch-mode battery charger designed specifically for 2-cell series Li-Ion or Li-Polymer stacks. The I²C interface lets the host microcontroller set charge voltage, current, and termination thresholds dynamically — no resistor dividers to swap for different battery chemistries.

Fault protection and temperature grade

On-chip fault protection covers over-current, over-temperature, and short-circuit conditions — these are hardwired safety limits that operate independently of the I²C register settings, so a firmware crash does not disable the protection.

25-DSBGA footprint — layout consideration

The 25-DSBGA package (0.5 mm pitch, 0.25 mm ball diameter) is a fine-pitch wafer-level package. Surface-mount assembly only; no hand-soldering this package.

Frequently asked questions

What is the difference between BQ25882YFFR and BQ25882YFCR?

The suffix difference — YFFR vs YFCR — typically indicates a packaging or reel quantity variant within the same BQ25882 base product. Both share the same 25-DSBGA package and I²C-controlled 2-cell charger function. The exact difference (tape width, reel diameter, or quantity) is specified in TI's ordering guide for the BQ25882 family. For a BOM line, confirm which exact ordering code your preferred distributor stocks.

Can BQ25882YFFR charge two Li-Ion cells in series?

Yes — the device is specified for 2 cells, meaning it regulates the charge voltage for a 2-series Li-Ion stack (typical 8.4 V full-charge). The I²C interface allows programming the target voltage per the battery manufacturer's specification.
