Charging management chip charging battery based on switching charging and direct charging and Operating method thereof

摘要

Disclosed are a charge management chip for charging a battery based on switching charging and direct charging, and a method of operating the same. A charging management chip according to an aspect of the technical idea of the present disclosure receives charging power from an external charger, bypasses and outputs the charging power through a first node, and in an electronic system in which the charging management chip is adopted. Receiving the charging power applied to the first node through a switching charging circuit and an input node that generates a used system voltage and charges a battery according to a switching charging method, and based on the switching operation of the internal switching circuit A first including a direct charging circuit for charging the battery according to a direct charging method by providing the charging power to the battery through an output node, wherein the switching charging circuit includes an inductor disposed outside the charge management chip. The battery is charged according to a charging path, and the direct charging circuit charges the battery according to a second charging path for directly providing charging power delivered to the output node to the battery.
