Reverse Polarity Protection
The classic approach to reverse polarity protection (left) introduces a diode drop which could be significant for low-voltage circuits. A better approach at right uses a P-Channel MOSFET. We could always replace the standard diode with a Schottky diode which has a typical forward drop in the range 0.2V – 0.5V.
