Abstract

An exemplary embodiment provides a charging method. The charging method includes detecting a charging current and producing a current-detecting signal according to the charging current; comparing the current-detecting signal with a first reference voltage and producing a current comparison signal accordingly; producing a second reference voltage according to the current comparison signal; comparing a battery voltage of a battery with the second reference voltage and producing a voltage comparison signal accordingly; producing a set of control signals according to the voltage comparison signal; and producing an adjusted charging voltage according to the control signals and a charging voltage, wherein the charging current is produced by the adjusted charging voltage to charge the battery.

Description

technical field [0001] The invention relates to a charging device, in particular to a single-circuit charging device. Background technique [0002] In recent years, with the massive growth of applications of portable electronic products, such as mobile phones, PDAs, music players and other applications, the use of rechargeable batteries has become more and more common. Rechargeable batteries can provide a stable voltage and current to make portable electronic products or circuits work normally. When the energy of the battery gradually decreases, the battery voltage will also begin to gradually drop. When the battery voltage drops below a certain voltage, the portable electronic product or circuit will not work normally. Therefore, the rechargeable battery provides a rechargeable function, so that the rechargeable battery can be used repeatedly. There are various types of rechargeable batteries currently on the market, and how to provide a fast and safe charging method for...
