Circuit Protection
Short Circuit (over Current)
Short circuit protection is nearly instant protection against excessive currents or current beyond the
acceptable current rating of equipment.
PTC resettable fuse
Short Circuit Protection for (almost) Any Power Supply
Reverse Polarity
The proper way to make a reverse polarity protection circuit is by using a PMOS MOSFET.
A Schottky diode alone is an inefficient way to protect a circuit from reverse polarity because
it requires a constant flow of current through the Schotty diode, and the output voltage will be less
than the input due to the forward voltage drop of the diode.
