Oring circuit using mosfet
WitrynaThe drawback of this solution is the additional circuit effort which has to be spent to drive the n-channel MOSFET during normal operation. A charge pump circuit is needed to create the required offset on the Gate pin over the battery line. EMI is an issue because the oscillator of the charge pump circuit is switching the two MOSFETs. WitrynaORing isolation is not required to achieve sharing of current between paralleled power supplies, but may be desired for redundancy in case of a power supply fault. The reference design in the schematic below shows how it may be implemented for the full-power main output, using FETs for low voltage drop.

Witryna14 lip 2024 · In the context of power supplies, when ORing is used, the output (the device) is powered by whichever supply typically has the highest voltage. A simple power OR gate can be made by diodes in series with each supply, which prevent power from the higher voltage supply backflowing into the lower voltage supply.
