2.5A programmable charger for single-cell packs
It supports multi-chemistry cells including Li-ion and Li-polymer, with a maximum battery pack voltage of 4.44V. Integrated fault protection covers over-temperature, over-voltage, and short-circuit conditions, reducing the need for external supervisory circuitry.
I²C programmability and system integration
The I²C interface allows the host microcontroller to set charge current, termination threshold, and timer values dynamically during operation. Supply voltage range extends to 10V max, accommodating standard USB and 5V wall adapter inputs without an external pre-regulator.
49-DSBGA footprint and rework considerations
Surface-mount assembly with Tape & Reel (TR) delivery; the small pitch requires a solder mask defined pad layout per TI's application note.
