Abstract
A charging integrated circuit (IC) includes: a connection circuit configured to selectively connect a first battery and a second battery to each other in series and in parallel; a first charger configured to charge the first battery and the second battery connected to each other in parallel in a first charging mode; and a second charger configured to charge the first battery and the second battery connected to each other in series in a second charging mode. The connection circuit may include: a first regulating circuit connected to the first battery in series and configured to regulate a first balancing current flowing to the first battery; and a second regulating circuit connected to the second battery in series and configured to regulate a second balancing current flowing to the second battery.
