I want to design H-bridge to drive 12V DC Motor at rate of 12A with Pulse Width Modulation
but the problems is the FETs which can drive the motor with that high current are N-ch (The P-ch is so expensive because it's extremely rare in my area) so I have to put 4 N-ch FETs in the H-bridge and 12V battery to drive the motors
But the problems is how to drive the gates of FETs correctly? and how the circuit will be?
(I've got a Microcontroller which can give me only 5-0V pulse,and one 12V battery)
