I am new to electronics and this is my first post
Situation:
I would like to build my first robot as a summer project. Nearly all the mechanical part is complete(waiting for a piece) and now I'm turning my focus to the electrical side. I'm using Proteus 8.6 Demo. to draw the circuit and simulate.
Information:
-My inputs are coming from a RF receiver with a PT2262 decoder, with the module I have, I'm unable to send ore then two signals and no PWM.
-The motors are 12V brushed gear motors, each of them have a stall current of 2.19A.
-My power supply is a 12V 5.5A lead acid battery.
Problem:
When one input goes high, the opposite mosfets get really hot and eventually die out. I know it may seem like a silly problem but I cant seem to find the cause of it
Questions:
Can someone please explain to me what might be happening and why?
If there are any improvements or a way to "fix' the circuit that you might recommend?
Is there a way to calculate the pull-up/down resistors and filter capacitor, for a further time?
I am unable to get any other parts for this project, I do have a backup 2A L298N dual h-bridge motor driver module, just in case.
All help is appreciated!
