Product details

Single-cell charger with 4A fast-charge and 14V input ceiling

The Texas Instruments BQ25898YFFT is a MaxCharge™ single-cell Li-Ion/Polymer battery charger IC rated for a 4A maximum charge current and accepting up to 14V on the supply input.

The 4A max charge current is the fast-charge ceiling for a single cell. The I²C interface lets the host reduce current for smaller cells or thermal management.

The part is ROHS3 compliant. For a production BOM this means stable supply without forced redesign — though the 42-DSBGA package means you are committed to that footprint and assembly process.

Frequently asked questions

Does BQ25898YFFT support USB PD?

The part lists I²C and USB as its interface. The 14V input max covers standard USB-C PD voltage levels, but the evidence does not specify explicit USB PD protocol negotiation. The host MCU handles PD policy via I²C.
