as i know Reverse polarity protection can be done only by using a simple diode, but i have checked few article and found that it is better to use a MOSFET instead of Diode.
Because voltage drop across diode is high. but i have tried the circuit with a general P-Channel MOSFET and after some calculation i found that the voltage drop is not much lower than the voltage across across diode..
i might be wrong, as i dont know how to choose the correct P-channel MOSFET,
of what parameter should be take care of...
Can anyone suggest me a best suitable P-Channel MOSFET for reverse polarity protection?
also, if it is possible with P-channel then i think its also possible with N-channel, what are the benefits of using these different methods...?
