I desiged P-MOSFET for reverse voltage protection, without gate resistor.

The reason that I tend to use it is protect from reverse DC voltage when someone connects the battery. Do I need a gate resistor? (When someone connects the battery correctly it will be in the ON state, otherwise the PMOS will be OFF.)

Second question:

How does a gate resistor reduce ringing?

  • Show your schematic design; embed an image so everyone knows exactly what you are talking about. Battery voltage range and output current range values are needed. – Andy aka Dec 03 '20 at 11:33
  • its a simple voltage circuit protection with dc input that could connect from ATX Power supply(12v) its okay for datasheet... @Andyaka – Knowledge Dec 03 '20 at 11:49
