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 ...

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 ...

Many battery-powered applications use diodes for reverse-battery protection. However, a diode does not always protect a battery charger when the battery is inserted incorrectly. Sometimes when the ...

In this circuit, a MOSFET protects a reverse-connected battery from excessive current. The MOSFET conducts only when the battery is correctly connected, which lets the battery charge or discharge. In ...

It's vital that MOSFET power-switch drivers be protected from a reverse-battery connection. A small rectifier diode can shield against reversed batteries. But that approach is generally unacceptable ...

Using a MOSFET as an ideal diode can provide robust and reliable safety protection for the emerging generation of autonomous appliances, as Shane Timmons explains. The growing popularity of cordless ...
