There are some well known techniques for handling source voltage reversal. The most obvious is a diode from the source to the load, but it has the downside of extra power dissipation due to the diode forward voltage. As elegant as it is, a diode will not work in portable or backup appli...

A reverse current inhibitor includes: at least one diode that is bridged by a first variable resistance element; a sensing circuit; a first switching device for switching the first variable resistance element from a first higher resistance to a second lower resistance in response to a forward ...
TPS2124: Reverse protection diodeLeonardo Sandler Prodigy 160 points Part Number: TPS2124 Hi, We want to use this TPS2124, with the diode for reverse voltage protection. From the datasheet we do not understand the expected current that will flow through this diode. ...
Functions like a diode in this application. Choose the pmos device based on current and voltage ratings, AND the on resistance Rds(on)- the lower the better, around .025 ohms is good. Vdrop= I2R Note that the transistor is reversed in this application, normally the Source would be posit...

If by reverse voltage, you mean when VOUT>VIN, but VIN>0, then yes, it will cutoff the FET in this situation. If you need both, you can utilize a strategy with a PMOS/diode or LM66100 in RPP config, followed by a second one. Another poster had found that...

PROBLEM TO BE SOLVED: To provide a simply-structured reverse voltage protection device capable of protecting an electronic apparatus from reverse connection of a battery without causing the problem of voltage drop due to a reverse voltage blocking diode. ;SOLUTION: A relay switch 16c of a self-ho...
It comprises primarily a series connection of a diode with its cathode connected to the high voltage of the power supply, connected through a NPN transistor which is connected to the junction between the load and the electronic switch. The control electrode of the NPN is operated by a PNP ...
