More Information

The BQ25980 is a 98.6% peak efficiency, 8-A battery charging solution using dual-phase switched cap architecture for 2-cell Li-ion battery. The switched cap architecture allows the cable current to be half the charging current, 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.
