It uses a constant-current, constant-voltage (CC/CV) charging profile with the charge current set via the I²C interface. It comes in a 49-DSBGA (2.8x2.8) package for compact portable designs.
I²C-programmable charging for design flexibility
The I²C interface lets the system host set charge current, termination threshold, and other parameters in real time, which is useful for dynamic charging profiles or for supporting multiple battery chemistries on the same board. The charge current is constant and programmable, with a maximum of 2.5A — enough for fast charging a single-cell pack in a tablet or power bank.
Fault protection and thermal range
Built-in over-temperature and over-voltage protection reduces external component count and improves system reliability.
The small footprint suits space-constrained designs, but the BGA requires careful PCB layout and X-ray inspection for solder joint verification.
