IR2104 for DC motor control

Hi every one !!!!!!!!!

I want to use the IR2104 as a MOSFET gate driver for H bridge that controls a DC motor. However I want to do so using one PWM input and a GPIO pin of my PIC microcontroller. I went through the datasheet and came up with the below circuit. Can someone please look into it and tell me whether it will work or not (before I bread board it and burn my MOSFETs and drivers)?


Regards

The problem with using it is that if you want the bridge to be on 100% for a long period of time the booststrap capacitor will discharge so the top fet won't stay on. You need one with a charge pump like the HIP4060 for it to work at DC.
