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 Schottky to Ground method is nearly identical to the Diode to Ground method described above. It requires that the potential source of reverse polarity be well understood, and that the Schottky be ...

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 ...

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 ...
