This article presents the reverse polarity protection for DC/DC converters. It describes the series diode protection, as well as the shunt diode, and P-FET polarity protection circuits. This article ...

This is a guest article by Adrian Mikolajczak of Fairchild Semiconductor. Reverse polarity, which is the result of a steady-state reverse bias or a negative transient, can cause serious problems in an ...

When I inspect houses where an amateur has been doing electrical work, there's a good chance that I'll find outlets with reversed polarity. This happens when the hot and neutral wires get flipped ...

Nexperia has put an ideal diode, including its p-channel mosfet, and reverse polarity protection, in a 2.1 x 1.25 x 0.95mm TSSOP6 package. Called NID5100, it is aimed at industrial and consumer ...

Fairchild Semiconductor offers a new line of low-power, application-specific, reverse polarity protection switches which also feature optional over-voltage transient protection. Fairchild ...

Part of a home inspector's analysis of a home includes a look at the electrical outlets. Not only will this inspection see if there are any obvious defects with the electrical system, but it will also ...

Amphenol RF has added reverse polarity (RP) SMA connector options to its RG-178 cable assemblies with right-angled AMC connectors on the far end, for Wi-Fi 6, GPS and cellular applications. With ...

A special control IC that emulates a “smart diode” along with an external MOSFET allows positive inputs and prevents negative inputs for automotive and industrial applications. This new IC replaces ...

The sun's polarity is getting closer to flipping. The star's northern hemisphere's polarity has already reversed, and the southern hemisphere should follow suit soon, scientists say. Every 11 years or ...

[Big Clive] picked up a keychain battery to charge his phone and found out that it was no bargain. Due to a wiring mistake, the unit was wired backward, delivering -5 V instead of 5 V. The good news ...
