Abstract

A universal charging detector and a universal charging detecting method are disclosed hereon, wherein the universal charging detector is suitable for a charging device. The charging device is used for connecting with at least one electronic device through a universal serial bus. The universal charging detector comprises a voltage output unit, a current sensing unit, a current level detector and a state machine. The voltage output unit is electrically connected with the universal serial bus. The current sensing unit is used for converting the output current of the charging device to the universal serial bus to a sensing voltage. The current level detector is sued for outputting a detecting signal according to the level of the sensing voltage. The state machine is used for causing the voltage output unit to adjust the voltage between a first data signal end and a second data signal end of the universal serial bus according to the level of the detecting signal.

Description

technical field [0001] The present invention relates to a charger, and in particular to a universal charging detector and a universal charging detecting method. Background technique [0002] Chargers are widely used in various fields, especially in the field of life, they are widely used in common electrical appliances such as mobile phones and cameras. The charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. The charger has a wide range of application prospects in the occasions where the battery is used as a working power source or a backup power source. [0003] However, the chargers using USB connectors nowadays have different specifications and are incompatible with each other, resulting in a wide variety of hardware charging types, making the demand for USB chargers complicated. [0004] It can be seen that the above-mentioned existing charging mech...
