The first virtual line (VL1) may be parallel to the second virtual line (VL2).

[0123] The first permanent magnet (131) disposed on the upper surface (101U) of the printed circuit board may be disposed on an imaginary line (CL) extending upward from the center of the first terminal (110) and the second terminal (120). The first permanent magnet (131) may be positioned on the center line (CL) of the first imaginary line (VL1) and the second imaginary line (VL2).

[0124] As illustrated in reference numeral 740, the first permanent magnet (131) disposed on the upper surface (101U) of the printed circuit board and the third permanent magnet (141) disposed on the lower surface (101D) of the printed circuit board may be disposed on a center line (CL).

[0125] FIG. 8 is a diagram illustrating an experimental process and result related to electrical connection between a power driver and an external electronic device according to an embodiment of the present invention.

[0126] Figure 8 illustrates simulation results (830) for power supply and communication signal transmission between a host device (810) and a slave device (820) connected via a single communication line. The host device (810) may correspond to an external power supply device (300), and the slave device (820) may correspond to a power driver (200).

[0127] When connecting an external electronic device (300) using an interface device (100), the connection can be made regardless of direction and polarity.

[0128] In a state where the host device (810) and the slave device (820) are connected, in the simulation result (830), the reference symbol 831 indicates a waveform when the slave device (820) generates a signal on the power line and the power line changes, the reference symbol 832 indicates power supplied to the slave device (820), and the reference symbol 833 indicates power supplied to the host device (810).

[0129] Among the essential components for communication, the host device (810) and the slave device (820) can be designed to communicate by integrating +power, Tx (transmission), and Rx (reception) into one, and having two ground lines to match the common potential between the two devices.

[0130] Meanwhile, the circuit may include a bridge diode. The bridge diode can eliminate the directionality of the + / - input.

[0131] The present invention described above can be implemented as computer-readable code on a medium having a program recorded thereon. Computer-readable media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid-state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices. Furthermore, the computer may include a processor or a control unit. Therefore, the above detailed description should not be construed as limiting in any respect, but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
