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 ...

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 ...

When a circuit requires reverse-voltage protection on the power input, the usual approach is a series diode (see the figure, a). But if the input voltage is low—say, two or three AA batteries—the ...

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 ...
