Product details

Package and mounting

The BQ25122YFPT ships in a 25-bump wafer-level chip-scale package (DSBGA). The PCB land pattern must follow the TI-recommended footprint.

300 mA charge current and 4.65 V termination

This is a linear charger for a single Li-Ion cell, rated for a maximum charge current of 300 mA and a maximum battery regulation voltage of 4.65 V. The I²C interface lets the host set the exact regulation point via the programmable current and voltage registers.

Industrial temperature range and fault protection

On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions. The supply input accepts up to 5.5 V.

Frequently asked questions

Does BQ25122YFPT work with 1-cell Li-Ion batteries?

Yes, it is designed for single-cell Lithium Ion batteries. The maximum battery regulation voltage is 4.65 V, which covers standard 4.2 V and 4.35 V Li-Ion chemistries. The I²C interface lets you program the exact charge current and termination voltage to match the cell specification.

What package is BQ25122YFPT?

The BQ25122YFPT is supplied in a 25-bump wafer-level chip-scale package, designated as 25-XFBGA or DSBGA. The supplier device package is 25-DSBGA.
