<p>A circuitry protection arrangement is disclosed, which is connectable to first and second power-consuming circuitry, wherein the first and second power-consuming circuitries are arranged in parallel and are connectable to a power source. The circuitry protection arrangement is adapted to protect the second power-consuming circuitry from over-powering and it comprises a controllable connection arranged to be connected in parallel with the first and second power-consuming circuitry when the circuitry protection arrangement is connected to the first and second power-consuming circuitry. The controllable connection has at least first and second operation modes, wherein the first operation mode enables a current flow through the controllable connection, thereby limiting at least one of a maximum voltage over and a maximum current through the second power-consuming circuitry, and the second operation mode disables the current flow through the controllable connection. The circuitry protection arrangement also comprises control circuitry adapted to detect an over-power situation of the second power-consuming circuitry and, in response thereto, set the controllable connection to the first operation mode.</p> |
