  • External battery and driving method thereof
    Patent number: 9768633
    Abstract: An external battery and a driving method thereof are disclosed. In one aspect, the external battery includes a battery, a charging unit, a detecting unit and a main controller unit (MCU). The charging unit generates a charging current using external power supplied from an external charger to an input stage, and provides the charging current to the battery or to an external device. The detecting unit detects whether the external charger and the external device are both coupled to the external battery. The MCU controls the charging current to be provided to the external device, when the external charger and the external device are both coupled to the external battery. Accordingly, when the external charger and the external device are both coupled to the external battery, the external device can be directly charged using the charging current applied from the external charger.
