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 ...

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 ...

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 ...

Different reverse-polarity solutions and their effectiveness at providing car battery front-end protection. How a smart diode controller can provide optimal reverse-battery protection. If the battery ...
