Mobile device charging system and related adaptive power converter and charging control circuit

Abstract

The invention provides a mobile device charging system and related circuits. A mobile device charging system includes a mobile charger and a mobile device. The mobile charger includes: an adaptive power converter for receiving data signals and generating a DC signal; an output terminal; and a charging cable for transmitting the data signals and receiving the DC signal to provide an output signal at the output terminal. The mobile device includes: a device-side connector for receiving power transmitted from the output terminal; and a charging control circuit for generating and transmitting the data signals to the adaptive power converter through the device-side connector and the charging cable. The adaptive power converter adjusts the magnitude of the DC signal according to the data signals to control the voltage drop of the charging cable to be less than a predetermined threshold. The mobile device charging system ensures charging speed and safety of a mobile device.

Description

technical field [0001] The invention relates to a mobile device, in particular to a mobile device charging system and related adaptive power converter and charging control circuit. Background technique [0002] The battery capacity is the main bottleneck affecting the usage time of the mobile device, and the time required for charging the mobile device is directly proportional to the battery capacity. Increasing the current transmitted by the charging line can speed up the charging of the mobile device, but a larger current can easily cause the charging line or related connection terminals to overheat and cause danger. [0003] In order to avoid danger during the charging process, the circuit components in the traditional charging device and the charging cable must be matched in specifications in advance, so the charging device can only be used with a dedicated charging cable, so users are not allowed to replace the charging cable with different specifications. Since the st...

Problems solved by technology

Increasing the current transmitted by the charging line can speed up the charging of the mobile device, but a large current can easily cause the charging line or related connection terminals to overheat and cause danger

[0003] In order to avoid danger during the charging process, the circuit components in the traditional charging device and the charging line must be matched in advance, so the charging device can only be used with a dedicated charging line, so users are not allowed to replace charging lines of different specifications

Because the structure of the traditional charging device severely limits the replacement flexibility of the charging line, the convenience and application range of the charging device are greatly reduced.
