Abstract: 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.

Abstract: 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.
