Abstract
A control circuit for indirectly limiting a load current which flows through a controllable semiconductor component. The control circuit controls the controllable semiconductor component based upon a measured and/or a calculated load-current-dependent power loss of the semiconductor component. The control circuit can also control the controllable semiconductor component based upon a measured and/or a calculated load-current-dependent component temperature of the controllable semiconductor component. A charging circuit includes a controllable semiconductor component for limiting a load current and has a control circuit in accordance with the invention. A motor vehicle includes an on-board electrical power supply system having a charging circuit in accordance with the invention.
