It operates from a supply up to 14V and includes over-current and over-temperature fault protection. The device comes in a 42-pin DSBGA package (2.8x2.5 mm) for space-constrained portable designs.
The 42-DSBGA package (2.8x2.5 mm) requires careful PCB layout for thermal management at 4A charge current — ensure adequate copper area and via stitching under the thermal pad.
The maximum charge current is 4A, which allows fast charging of a single Li-Ion or Li-Polymer cell within the thermal limits of the 42-DSBGA package.
No. The BQ25898DYFFT is designed for single-cell (1S) Li-Ion/Li-Polymer batteries only, as indicated by the Number of Cells specification of 1.
