I will just omit C3. I didn't realize it was a problem. I added C1 thinking that was what you meant to do. C3 is just what I put next to all chips I use as a decoupling cap. I didn't know it was interfering with the P channel MOSFET. Thanks for explaining that. I kinda understand it now.
I'll be sure to turn the h bridge signals off before turning off the P channel.
Thanks!
Just bear in mind that C1 is effectively the decoupling cap for the H-bridge, so it should be close to the chip and the traces between it, the chip and the P-channel mosfet should be kept short. If you are making a PCB, then I suggest you make a space for C1 anyway (and a capacitor in parallel with R2), just in case there are any problems with noise pickup when the mosfet is off.
