Charging detection and control apparatus for apple device

A charging detection and control apparatus for an Apple device, comprising a charging input interface (21), a detection apparatus (22), a control apparatus (23), a charging output interface (24), a signal option switch (25) and a switch control apparatus (26), wherein a charging source terminal (1) is connected to an input terminal of the detection apparatus (22) and a first port (251) of the signal option switch (25) respectively via the charging input interface (21), an output terminal of the detection apparatus (22) is connected to an input terminal of the control apparatus (23), an output terminal of the control apparatus (23) is connected to a second port (252) of the signal option switch (25), a third port (253) of the signal option switch (25) is connected to the Apple device (3) via the charging output interface (24), and an output terminal of the switch control apparatus (26) is connected to a forth port (254) of the signal option switch (25),

• the charging detection and control apparatus for an Apple device supports a charging detection mode and a data transmission mode;
• in the charging detection mode, the switch control apparatus (26) shorts-circuit the second port (252) and the third port (253) of the signal option switch (25) via a control signal, the detection apparatus (22) detects a capacity for charging current of the charging source terminal (1) inserted into the charging input interface (21), and outputs a detection result to the control apparatus (23), the control apparatus (23) converts the received detection result into a charging parameter complying with Apple standards and sends the charging parameter to the Apple device (3) via the signal option switch (25) and the charging output interface (24), the Apple device (3) automatically regulates a charging load capacity according to the received charging parameter, thereby realizing an effect in which the Apple device (3) is charged with the maximum current,
• in the data transmission mode, the switch control apparatus (26) alternatively shorts-circuit the second port (252) and the first port (251) of the signal option switch (25) or shorts-circuit the second port (252) and the third port (253) of the signal option switch (25) via a control signal;
• when the second port (252) and the first port (251) of the signal option switch (25) are shorted-circuit, data communication can be carried out between the control apparatus (23) and the charging source terminal (1) via the data option switch (25) and the charging input interface (21);
• when the second port (252) and the third port (253) of the signal option switch (25) are shorted-circuit, data communication can be carried out between the control apparatus (23) and the Apple device (3) via the signal option switch (25) and the charging output interface (24), thereby realizing an effect in which the Apple device (3) is charged with the maximum capacity and satisfying a demand of data transmission at the same time.
