Figure 1 A series diode protects systems from reverse polarity but wastes power in diode losses. Figure 2 You can use a bridge rectifier so that your system works no matter what the input polarity is.

[Afroman’s] latest video shows you how to add reverse voltage protection with minimal power loss. At some point, one of your electronic concoctions will turn out to be very useful. You want to make ...

Author Jim Walker describes how to use a dual IRF7342 or IRF7341 in a circuit to supply low-voltage reverse-polarity protection A dual IRF7342 FET was used (p-channel, with both sides wired in ...

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 ...

If the car battery terminals are reverse connected during a jump start, vehicle upkeep, or repair, components in the associated automotive electronics modules may be damaged if they cannot handle the ...
