Hello
I'm trying to radio control a 24V 250W DC motor using Arduino. Instead of buying a real RC ESC I thought I might as well build an H-bridge myself and learn something along the way. I was thinking that I can use some logic level MOSFETs like the IRL7833 or something similar (this one is probably overkill but I don't know that much about MOSFETs).
This is my attempt at making one. The alternatives on ebay made me wonder if I missed something though.

That chip next to the half-bridge acts as an extra enable switch or something as I understand it. Is this correct? What do you reckon that capacitor is for? Do I need these extra components or will the circuit I made work? What do I do about the diodes if I want electrical braking? Any diodes that you can recommend for this?
Answers are appreciated as always!
Edit: If I don't use electrical braking for this I suppose I could just connect 1 with 3 and 2 with 4 so that I only use 2 of the Arduino's PWM pins
