Abstract: A charger integrated circuit is configured to charge a battery device including a first battery and a second battery connected in series. The circuit includes a direct charger configured to generate a first charging current and a first current based on an input voltage received from an input terminal, the first current used to generate a first system current, and a buck converter configured to generate a second current and a second system current based on the input voltage, the second current used to generate a second charging current. The circuit includes a switched capacitor configured to generate the first system current based on the first current, and to generate the second charging current based on the second current, and a linear charger configured to provide the first charging current and the second charging current to the battery device.
