GND protection network against reverse battery
This section provides two solutions for implementing a ground protection network against
reverse battery.
Solution 1: resistor in the ground line (R

This resistor can be shared amongst several different HSDs. Please note that the value of
this resistor should be calculated with formula (1) where I
