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 ...

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 ...

But with reversed polarity, the item can be energized even if you think it is off since electricity will flow through the circuit until it reaches the closed switch, rather than being cut off at 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 ...

The time it takes for Earth's magnetic field to reverse polarity is approximately 7000 years, but the time it takes for the reversal to occur is shorter at low latitudes than at high latitudes, a ...

[Big Clive] picked up a keychain battery to charge his phone and found out that it was no bargain. Due to a wiring mistake, the unit was wired backward, delivering -5 V instead of 5 V. The good news ...
