1.5 A charge ceiling for a 1-cell Li-ion pack
It accepts input voltages up to 13.5 V, covering USB and common adapter rails without a separate pre-regulator. Integrated fault protection — over-current, over-temperature, and over-voltage — reduces external monitoring components and simplifies the BOM for space-constrained portable designs.
I²C programmability and charge-profile flexibility
The I²C interface allows a host MCU to adjust the charge current and battery regulation voltage dynamically, enabling adaptive charging profiles for different cell capacities or temperature conditions. The charge current is constant and programmable, so the system can trade charge time against thermal budget.
