Tool/software:
Hi all, I'm new in designing H-bridge and face some design challenges.
I'm using UCC20225NPLR as my Isolated gate driver for H-bridge designs.
Grounding Questions:
Q1. Should I have a connect the separated ground from primary and secondary side using a net tie so they have a common reference? If yes, will the noise couple into the primary side?
I'm using INA241A1 as the current sense device in my design at the same time. I dragged the differential input voltage through a slit from MCU ground to gate driver secondary ground (Motor Driver ground).
Q2. Should I avoid doing this kind of practice? or should I use isolated current sense?
