Product details

It uses an I²C interface to set the charge current and the maximum battery pack voltage of 4.44 V, making it a fit for portable devices where the host microcontroller manages the charge profile.

Constant-current charging and fault protection

Yes, the BQ24187YFFR supports constant-current charging — the charge current is programmable via I²C, with a maximum of 2 A. The IC also includes over-temperature and over-voltage fault protection, covering the two most common failure modes in a single-cell Li-Ion charging path.

For existing BOM lines, last-time-buy inventory is exhausted through the factory channel; remaining stock is held by independent distributors and surplus brokers.

36-DSBGA package — layout and rework notes

The fine-pitch BGA requires a solder stencil with small apertures and a reflow profile matched to the 0.4 mm ball pitch. For rework, a hot-air nozzle with a matching footprint and pre-bake per J-STD-033 are recommended.

Frequently asked questions

Where can I buy BQ24187YFFR and how do I get a price?

The BQ24187YFFR is obsolete and no longer available through the factory channel. We source it through independent distribution and surplus inventory. Submit an RFQ — we confirm availability and current pricing at quote time.
