Abstract
A semiconductor fuse for disconnecting an electric consumer from an energy supply source for a battery electric vehicle includes at least one semiconductor switch element that is connected between the energy supply source and the electric consumer. The semiconductor switch element includes a gate control terminal for controlling a switch-on and switch-off of the semiconductor switch element. The semiconductor fuse includes: a driver circuit for applying a driver voltage that is lower than a predetermined gate threshold voltage of the semiconductor switch element at the gate control terminal of the at least one semiconductor switch element; a measurement circuit for determining a gate charge at the gate control terminal; and a control system that detects a drift of the gate threshold voltage based on the gate charge and indicates an issue with the semiconductor switch element based on the detected drift of the gate threshold voltage.
