Description
General part information
BQ25980 Series
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.
The BQ25980 also supports 7-A bypass mode charge (previously called battery switch charge) through internal MOSFETs. The Rdsonin bypass mode charging path is less than 13mΩ for high current operation. The integrated bypass mode allows backward compatibility of 10-V fast charging adapter to charge 2-cell battery.
The device supports dual input configuration through integrated mux control and driver for external N-FETs. It also allows single input with no external N-FET or single N-FET.
