摘要： Embodiments relate to a device and method for protecting an electrical system component of a vehicle electrical system. The device comprises a semiconductor switch connected to the electrical system component. A circuit connected to the semiconductor switch comprises a detection unit for detecting an electrical malfunction of the vehicle electrical system and an activation unit for activating the semiconductor switch. A control unit communicatively connected to the circuit is configured to switch the semiconductor switch into a first safe state, in which the semiconductor switch is switched off, based on the detection of an electrical malfunction, and to selectively switch the semiconductor switch into the first safe state or into a second safe state, in which the semiconductor switch is switched on, based on at least one predetermined vehicle state.

摘要： A current flows between the drains of FETs, which function as a switch. A first constant current circuit causes a constant current to flow from the FET side of a resistor to the other side thereof. A first comparator outputs a high level voltage to the control section if the electric potential at the drain of the FET is higher than the electric potential at one end, on the first constant current circuit side, of the resistor. Furthermore, the first comparator outputs a low level voltage to the control section if the electric potential at the drain of the FET is lower than the electric potential at one end, on the first constant current circuit side, of the resistor. The control section turns the FETs off when the first comparator outputs the low level voltage. Furthermore, the control section changes the current that is caused to flow through the resistor by the first constant current circuit.

摘要： An assembly for electrical protecting a potential short-circuit path in a power network having an energy store and having a system-determined, variable source internal resistance. The assembly includes a separating element, the triggering characteristic of which is insufficiently sized for protecting a first and second conductor section of the potential short-circuit path in a first operating state of the energy store, and a second protection device, which is configured to protect the first and second conductor section against a load which occurs below the triggering limit of the separating element in the first operating state.
