Product details

2A single-cell charger with I²C and USB control

The battery pack voltage ceiling is 4.44V, covering standard 4.2V and 4.35V Li-ion cells. Fault protection includes over-temperature and over-voltage shutdown.

NRND — plan the last-time-buy window

Buyers should confirm the last-time-buy schedule and evaluate a migration path before the part enters full obsolescence.

30-DSBGA package and operating range

The device comes in a 30-DSBGA package, a 0.4 mm pitch wafer-level chip-scale package that requires careful PCB layout for thermal and solder-joint reliability. The mounting type is surface mount, supplied on Tape & Reel.

Frequently asked questions

How can I order BQ24257YFFR or check stock?

BQ24257YFFR is NRND — we can source it against your BOM quantity and confirm current pricing and lead time at quote. Submit an RFQ through the site; availability is confirmed per order, not held on the shelf.

Is BQ24257YFFR obsolete or End of Life?

The part carries an NRND status from Texas Instruments — not yet End of Life, but not recommended for new designs. A last-time-buy window may be open; check with your TI representative for the official EOL timeline.

What is the maximum charge current of BQ24257YFFR?

The maximum charge current is 2A, programmable via the I²C interface. The actual charge current is set by the host controller and limited by the thermal capability of the 30-DSBGA package.

What is BQ24257YFFR's listed interface?

The device supports I²C and USB control interfaces. The I²C bus is used for charge parameter programming and status monitoring; the USB input accepts standard USB voltage levels.
