2.5A programmable charge current with I²C control
Fault protection covers over-temperature and over-voltage conditions, making it suitable for portable devices that need a host-controlled charging profile.
Where it fits in the charging cycle
This part sits between a 10V max supply rail and a single Li-Ion or Li-Polymer cell. The I²C interface lets a system MCU set the charge current dynamically — useful for thermal management or USB input current limiting.
Housed in a 49-DSBGA (2.8x2.8 mm) package with surface-mount termination. The 0.50 mm ball pitch and small footprint demand a controlled-impedance PCB stack and careful thermal via placement under the package. The supplier device package is 49-DSBGA (2.8x2.8).
