Abstract: One embodiment provides a vehicle voltage supply having a vehicle battery, a load with two voltage supply connections, a fuse in a path between the vehicle battery and one of the voltage supply connections of the load, and a clamping circuit transistor. The clamping circuit transistor can be switched in such a manner that the clamping circuit transistor produces a short circuit between voltage supply connections of the load in order to activate the fuse. An energy store is set up to store the energy needed to drive the clamping circuit transistor when producing the short circuit, and a charging circuit is set up to charge the energy store at least during the time in which the clamping circuit transistor does not produce a short circuit.

Abstract: A communication network is described comprising a first bus interface, a second bus interface, a bus which connects the first bus interface and the second bus interface, one or more receivers connected to the bus, a detector configured to detect whether a first message transmitted via the bus by the first bus interface has reached the one or more receivers; and a controller configured to, if the first message has not reached the one or more receivers, control the second bus interface to transmit at least one second message to at least one of the one or more receivers via the bus.

Abstract: 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.

Abstract: A semiconductor module includes a housing with at least one semiconductor component that is conductively connected to at least one output line. An integrated temperature sensor is also housed in the housing. This sensor is connected, via at least one of its load terminals, to a terminal for receiving a supply potential. The temperature sensor conducts a load current that heats-up the temperature sensor when a first temperature threshold is crossed and a supply potential is in being supplied. A housed interruption device is arranged in such a way that it interrupts the output lines carrying the load current when a second temperature threshold has been exceeded.
