CHARGING MANAGEMENT CHIP FOR CHARGING BATTERY BASED ON SWITCHING CHARGING AND DIRECT CHARGING, AND OPERATING METHOD OF CHARGING MANAGEMENT CHIP - A simplified explanation of the abstract

This abstract first appeared for US patent application 17990647 titled 'CHARGING MANAGEMENT CHIP FOR CHARGING BATTERY BASED ON SWITCHING CHARGING AND DIRECT CHARGING, AND OPERATING METHOD OF CHARGING MANAGEMENT CHIP

Simplified Explanation

The abstract describes a charging management chip that includes a switching charging circuit and a direct charging circuit. The switching charging circuit charges a battery using a switching charging method and controls the system voltage provided to an electronic system. The direct charging circuit charges the battery using a direct charging method by providing the charging power directly to the battery.

• The switching charging circuit receives charging power and charges the battery through a first charging path that includes an external inductor.
• The direct charging circuit receives the charging power applied to the first node and charges the battery through a second charging path by providing the charging power directly to the battery.
• The switching charging circuit controls the generation of the system voltage provided to the electronic system.
• The direct charging circuit utilizes a switching circuit to transfer the charging power to the output node and then provide it directly to the battery.

Potential Applications

• This technology can be used in various electronic devices that require battery charging, such as smartphones, tablets, laptops, and wearable devices.
• It can be implemented in electric vehicles and hybrid vehicles for efficient battery charging.

Problems Solved

• The charging management chip solves the problem of efficiently charging a battery by providing both switching charging and direct charging methods.
• It addresses the issue of controlling the system voltage provided to the electronic system for optimal performance.

Benefits

• The switching charging circuit allows for efficient charging of the battery through the use of an external inductor.
• The direct charging circuit provides a direct path for charging power to the battery, improving charging efficiency.
• The chip's ability to control the system voltage ensures optimal performance of the electronic system.
• The technology offers flexibility in charging methods, allowing for efficient and fast charging of batteries.

Original Abstract Submitted

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.
