11-1 Reverse Polarity Compatibility
The LGDS-300 has been designed to be compliant with reverse polarity requirements. The reverse polarity protection can
be externally achieved either by a standard solution using a schottky diode or either a low losses solution using a N
channel power MOSFET. The following figures are showing both solutions.
