    摘要： A vehicle on-board electric power system is disclosed including at least one field-effect-controlled power transistor which applies a vehicle on-board electric power system supply voltage VBB to a load when actuated by a logic circuit. The power transistor has a drain-source breakdown voltage VDS with a positive temperature coefficient TKDS and is provided with a clamping means for protecting against overvoltages VO occurring in the vehicle on-board electric power system. The clamping means has a clamping voltage VCLAMP with a positive temperature coefficient TKCLAMP≈TKDS, the clamping voltage VCLAMP being lower than or equal to an anticipated maximum overvoltage VOmax in the vehicle on-board electric power system.

    摘要： A circuit arrangement includes a semiconductor switch having a control terminal and a load path. A drive circuit is coupled to the control terminal of the semiconductor switch. The drive circuit has a current measuring arrangement for determining a load current flowing through the load path and is designed to prevent the semiconductor switch from being driven in the off state if the load current exceeds a predetermined load current threshold value. A fuse is coupled in series with the load path of the semiconductor switch triggers if a triggering condition dependent at least on the load current is present.

    摘要： An apparatus for generating a power signal from a load current is described, has a controller with a load current input, a load current output, an intermediate signal output, and a status signal output, an influencing device with an intermediate signal input and a power signal output, and an interruption device with an interrupt input, an interrupt output, and a status signal input. The controller generates a status signal and an intermediate signal depending on the load current, and the interruption device interrupts the power signal if the status signal satisfies a predetermined first condition, and otherwise lets the power signal pass, and the influencing device generates the intermediate signal as the power signal and output the same at the power signal output if the intermediate signal does not satisfy a predetermined second condition, and otherwise generates and output a power signal with a predetermined value.
