摘要： In one embodiment, a circuit couples an integrated circuit to a powerline and protects the integrated circuit from overvoltage noise. In one example, the integrated circuit comprises a two-port differential transceiver. Respective Schottky diodes couple the ports to a power supply and reference, so one diode for each port conducts current in forward bias if an applied voltage exceeds a respective voltage reference plus the forward voltage of that diode. A respective end of a first transformer winding feeds each input port. Respective ends of a second transformer winding couple to capacitors that couple with the powerline. Back-to-back zener diodes are connected between the ends of the second winding. A zener diode with a breakdown voltage set based on the power supply voltage plus a margin is coupled between the power supply and ground so that the power supply voltage does not exceed a desired value plus the margin.

摘要： In order to permit, in a motor vehicle on-board power system, data to be transmitted with low expenditure on cabling, even between multiple partial networks, a plurality of loads embodied, in particular, as sensors is respectively assigned a communication unit for transferring data. The communication units are embodied in such a way that, by utilizing the supply lines they set up a partially interlinked data network, and transfer data made available by the loads, with the result that communication via the partial networks is also made possible. As a result of the transmission of the data via the supply lines in combination with the setting up of a partially interlinked data network, signal transmission is made possible even if there is no direct connection between the respective sensor and a target unit.

摘要： A power supply system providing communication from a master module to at least one slave module via transients, to alter operation of a load, is provided. The master module output a supply voltage that is either a normal supply voltage or a reduced supply voltage. The outputted supply voltage depends on input corresponding to a communication to be sent to the slave module to alter operation of the load of the slave module. The slave module receives the supply voltage and interprets the received supply voltage, which may vary between the normal and reduced supply voltages, to determine what the communication from the master module is. The slave module then uses information from the communication to appropriately alter operation of its load.
