Abstract
A charging management chip includes a switching charging circuit and a direct charging circuit. The switching charging circuit receives charging power, and passes through the charging power to a first node, and charges a battery according to a switching charging method and controls generation of a system voltage provided to an electronic system. The direct charging circuit receives the charging power applied to the first node via an input node, and charges the battery according to a direct charging method by providing the charging power to an output node based on a switching circuit therein. The switching charging circuit charges the battery through a first charging path including an inductor arranged outside the charging management chip, and the direct charging circuit charges the battery through a second charging path through which the charging power transferred to the output node is directly provided to the battery.
