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 ...

It’s a problem that’s been around for as long as there have been battery-powered systems: you load the battery the wrong way, with the poles inverted, and create a reverse-polarity event. The system ...

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 ...

Members can download this article in PDF format. Power systems employ diodes to perform a variety of functions. For example, diodes can protect against damage due to power-source reverse-polarity ...
