Dear All , Have a nice day

I used IRPF150N MOSFET
IR2104 Driver

Using above i make a H bridge driver and it is working perfectly

My Question is

Can I able to drive two MOSFET using single IR2104 it is like picture is showing
What are the parameters that I should consider in this situation

Please advice
Thanks in advanced

You need to identify the drain and source terminals of the FETs and provide a power supply for them. The IR2104's only provide gate-drive signals, not power.

Maybe. Normally we keep the distance from driver to gate short.
Also there is a diode and capacitor that charges up to power the top side driver. I have not thought long and hard about it but I thing if one bridge has high current and the other low there might be a very bad cross connection. To say it differently, the bottom MOSFET(s) share a common ground Source connection and it will work. The top MOSFET do not share a common Source and I can see it will work well.
