MOSFET Reverse Battery Protection
You may not know how to use MOSFET as reverse battery protection. The most common method is using a diode. However, diode voltage drop is high and this will creat issue in low voltage circuits. That is the reason many use MOSFET as reverse battery protection due to its very low on state voltage drop.
