Hi there,
That's my first message on this forum.
I'm designing a motor control board based on the SM72295 gate driver.
My board is powered with two isolated supplies : dirty 50V supply for the motor, and a clean 12V for the embedded µC.
As the SM72295 requires 12V and 3.3V, my idea is to use the clean 12V power for that purpose, and use 50V for the power stage, but my grounds are isolated, and I'm not sure that I can keep them isolated (even if I don't need to have a high isolation level: 100V max).
Is that possible to design such board with isolated grounds based on a SM72295?
Regards,
Léo
