Power Supply Source Automatic Cognition and Charging Type Data Communication Cable

摘要

PURPOSE: A data communication cable is provided to prevent an overload and erroneous charging operation by automatically recognizing the power supply source connected to the data communication cable and controlling charging current in accordance with the power. CONSTITUTION: A data communication cable comprises a data port(101) for exchanging data with a terminal and supplying charging current to the terminal; a USB port(103) for transmitting data to the terminal and an external personal computer, and receiving charging power from the personal computer or receiving charging power from an external power supply; a cable(102) for converting the charging power received from the personal computer or the power supply into charging current, outputting the current to the data port, and transmitting the terminal data transmitted/received through the data port to the USB port; and a charging circuit unit(107) for automatically recognizing the power supply source connected to the USB port and automatically converting and controlling charging current.
