child Safety Mobile Charger

Abstract Mobile chargers are a common household accessory, but they present safety hazards when left plugged in. Exposed USB tips often retain a live 5 V, which may pose a risk to children. This project proposes a novel Child Safety Mobile Charger design in which the charger delivers 0 V at the USB-C tip unless a mobile phone is actually connected. The system integrates USB-C connection detection, a controlled load switch, and protection circuits. Safety is improved without compromising normal charging functionality.
