Field
The present disclosure relates generally to an electronic device, a cable, and a method of driving the same.
Description of Related Art
In general, a cable connects electronic devices and relays transmission and reception of data between electronic devices. Further, the cable may transmit power as well as data.
Nowadays, while demand increases for improved battery charge technology of an electronic device, a protocol that transmits power bi-directionally and a cable that supports the protocol are suggested. According to bi-directional power transmission technology, a user may connect different electronic devices using a cable and transmit power bi-directionally through the cable. For example, the user may connect a Moving Picture Experts Group layer-3 (MP3) player and a smart phone using a cable. Accordingly, the user may charge a battery of the smart phone with power stored at the MP3 player or may charge a battery of the MP3 player with power charged at the smart phone battery.
However, in conventional bi-directional power transmission technology, in order for a user to determine a present state such as a voltage magnitude and a current direction, the user should directly determine a connected electronic device.
