Abstract
A system having a load device coupled to an output of an electronic control unit (ECU) via a coaxial cable, and the ECU is disclosed. The ECU has a power supply configured to provide power for the load device, a power over coaxial cable (PoC) filter coupled to the output, a high side switch (HSS) coupled to the power supply and to the PoC filter via an HSS output line, and a diode disposed in the HSS output line and configured to substantially eliminate current flow from the output towards the HSS, while allowing current to flow from the HSS towards the load device from the HSS.
