I've read in a datasheet before about using a P channel mosfet as a "lossless" diode. forgot where though. I think it was connecting drain on + supply, source on load +, and gate on ground/common.
wiring supply backwards doesn't make the mosfet conduct and internal body diode is reverse biased so load is safe.
someone correct me if I remember wrong though.
Yes. Google for "p-channel mosfet reverse polarity protection", here's the first result I got:I've read in a datasheet before about using a P channel mosfet as a "lossless" diode. forgot where though. I think it was connecting drain on + supply, source on load +, and gate on ground/common.
