An electronic circuit arrangement may include a first supply line and a second supply line which are connectable with an electric energy supply unit at a first supply line input connection and a second supply line input connection. The first supply line and the second supply line may be electrically connectable at a first supply line output connection and a second supply line output connection with an external electronic device for supply of electric energy. The arrangement may include a switching element provided in the first supply line. The switching element may be switched between an opened sate, in which the switching element electrically interrupts flow of an electrical current in the first supply line, and a closed state, in which the electrical current flows uninterrupted. The electronic circuit arrangement may include a first electronic circuit, a second electronic circuit, and a third electronic circuit.
