Product details

It supports a maximum battery pack voltage of 4.44V and a programmable charge current up to 1.25A, with constant-current charging that adapts to the cell's needs. Fault protection covers over-temperature and over-voltage events, making it suitable for portable devices where the battery is handled by the end user.

Thermal and supply budget for portable designs

Operating from a 6V maximum supply rail, the charger can run directly from a 5V USB bus or a regulated wall adapter without an extra LDO. Packaged in a 20-DSBGA (20-bump wafer-level chip-scale) with 0.50 mm pitch, the footprint demands a controlled solder-paste stencil and a reflow profile matched to the DSBGA's smaller thermal mass.

Frequently asked questions

Is BQ24153AYFFR compatible with a standard 4.2V Li-ion cell?

Yes. The maximum battery pack voltage is 4.44V, which covers the 4.2V termination voltage of a standard Li-ion cell with margin. The I²C interface lets the host set the exact regulation voltage below the 4.44V ceiling.

Does BQ24153AYFFR have a pin-compatible alternative?

The base product number is BQ24153; any pin-compatible variant would share that base number and differ only in suffix. Confirm the exact suffix against your BOM.
