Abstract: An electronic circuit arrangement may include first and second electric connections connectable to first and second electronic devices, respectively. A first electric conduction path may connect the first and second electric connections, and a second electric conduction path may connect a tee point provided in the first electric conduction path to an electric ground connection. First and second switching elements may be provided in the first and second electric conduction paths, respectively, between the tee point and the respective electric connection. Each switching element may switch between an open state, in which the switching element may interrupt the respective electric conduction path, and a closed state. In response to connecting the second electronic device to the second electronic connection, the second switching element may switch to the open state, and the first switching element to the closed state only after the second switching element is already in the open state.

Abstract: 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 state, 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.

Abstract: An electronic circuit arrangement may include a first and a second electrical supply line for connecting an electronic device with a rechargeable battery. The first electrical supply line may be connected at one end with the rechargeable electric battery and at the other end with the electronic device for supplying electric energy. At least two switching elements may be provided in the first electrical supply line, which each may be switchable between an open state, in which the respective switching element electrically interrupts the first supply line, and a closed state. The electronic circuit arrangement may include a protective circuit arrangement and a reset circuit arrangement.
