The 3.2 A ceiling means a 2000 mAh cell can fill in under 40 minutes at the full rate, but the thermal budget in the 24-WQFN package demands a solid thermal via pattern under the exposed pad. Input supply tolerance goes up to 13.5 V, so a 5 V USB port or a 9 V adapter is fine, but a 12 V rail sits right at the edge — the designer should verify the absolute maximum rating in the datasheet before committing the BOM. ## Parametric fit for the battery and system The battery pack voltage range is 4.6 V to 5.15 V, which covers the standard 4.2 V Li-ion termination voltage plus a small constant-voltage taper window. The charger terminates when the current drops below the programmed threshold, not at a fixed voltage — the I²C register sets the timer and current limit. Fault protection is built in for over-current, over-temperature, and over-voltage events, so the host MCU does not need to monitor charge status continuously.
