The BQ25996 is a 98.3% peak efficiency, 16A battery charging solution using dual-phase switched cap architecture for 1-cell Li-ion battery. The switched cap architecture allows the cable current to be one quarter, one third, or one half of the charging current depending on converter mode and input voltage, reducing the cable power loss and limiting temperature rise. The dual-phase architecture increases charging efficiency and reduces the input and output cap requirements. When used with a main charger such as BQ25790, the system enables the fast charging at the very low power loss from pre-charge through constant current (CC), constant voltage (CV), and termination.

The BQ25996 also supports bypass mode charge through internal MOSFETs.

The device supports control and driver for external N-FETs or a single N-FET relative to a CMSRC regulation pin.
