Abstract
An overcurrent protection device comprises a maximum-allowed-current unit and a power switch. The maximum-allowed-current unit determines a maximum allowed current in real-time. The maximum allowed current is determined at least partially on an instantaneous level of a load voltage. The load voltage is a voltage across a load to be powered. The power switch is connectable with a switch input to a voltage supply and with a switch output to the load, for providing power to said load. The power switch has a conductive state and a nonconductive state, and is arranged to assume the nonconductive state in response to an indication that a current through the power switch is exceeding the maximum allowed current. A method of operating a power switch is also described.
