Hi, i am designing an h-bridge circuit to control a brushed dc motor and after trying to test this circuit out on the pcb i have failed to get the circuit to work. Only my low side MOSFETS turn on and the voltage on my high side fets remains in the mV range. I am unsure on what is happening, i have probed with a scope and traced my signals all the way to the input of my drivers and after the drivers the high side signal comes out very messy and in the mV range. I just want to understand if i did something wrong on my design or if there is something i am not understanding fundamentally. On the simulation everything comes out nicely, my high sides turn on and everything is fine, but on the pcb the high switches remain off.
For more context:
I am using an all N-MOS design, so 4 n-channel MOSFETs
The mosfets: ixfb210n30p3
The gate driver: dgd2190m
Any comments or suggestions would be greatly appreciated
