Anti-leakage supply circuit

An anti-leakage supply circuit comprising:

• a power supply unit configured to supply a supply voltage;
• an output unit coupled to the power supply unit;
• a control unit coupled to the output unit;
• and
• a control circuit couplable to an interface and the output unit;
• wherein the control unit is configured to output a control signal;
• wherein the output unit is configured to be switched on upon receiving the control signal, and to output an output voltage after being switched on and receiving the supply voltage;
• wherein the output unit is also configured to output an output voltage after being switched on and receiving the supply voltage;
• wherein the control circuit is further configured to be switched on after an electronic device is in a normal state;
• wherein the output unit is further configured to connect to the interface after the control circuit is switched on, thereby enabling the output unit to output the output voltage to supply to the interface;
• and
• wherein the control circuit is further configured to be switched off after the electronic device is in a shutdown state, thereby disabling the output voltage from the output unit to the interface.
