The invention relates to a reverse polarity protection circuit, to a device having such a reverse polarity protection circuit, and to a method for operating said reverse polarity protection circuit. The reverse polarity protection circuit has a MOSFET (1) and a blocking circuit, which blocks the ...
and electrolytic capacitors have a famous tendency to explode. For this reason, it’s common to use a blocking diode in a circuit to provide reverse polarity protection:
This diode prevents damage in the case of reverse polarity hookup by an experimenter. A couple of things to keep in mind when selecting a diode for use in your circuit: Choose a Schottky diode if you can. Schottky diodes have lower voltage drops and are usually better suited for low ...
The protection circuit works by interrupting the flow of power to the device’s electronic components, shielding them from electrical damage. Reverse polarity protection is particularly vital in industrial environments where DC power supply systems often deliver significant power. Without this safeguard, ...

Here is a plot of the transient and steady-state response of the Schottky-based reverse-polarity-protection circuit. You can see that the reverse current and the reverse voltage across the load are much larger than what we observed with the non-Schottky diode. This higher reverse leakage curren...
Here's a rough schematic of what our circuit looks like. The LM5050 is used as reverse polarity protection for INPUT 1, for INPUT / OUTPUT 2 we can't use that trick as it's an input as well as an output. There is reverse polarity protection to the internal system rail for bot...

installed backward, you must design either a mechanical block to the reverse installation or an electrical safeguard that prevents ill effects when the reverse installation occurs. Mechanical protection can be a one-way connector that accepts the battery only when oriented with the correct polarity. ...
