A previously-published Design Idea outlined a polarity protection circuit that provides the correct connection of the battery to a load regardless of the battery’s orientation in its holder. The ...

As they took him away, Clyde realized that leaving out that protection FET to save $0.35 had been a poor design decision. (Courtesy of Autoevolution) Electronics and automobiles have a long history ...

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 ...

Accidentally connecting a battery reverse can be a real killer in electronic circuits. There are a number of ways to provide protection and all have the expected advantages and disadvantages. Any ...
