Hi !


I have some questions about ADI gate driver.

Although it is recognized that the gate input side GND and the low side GND are connected with almost the same impedance, if there is a short state (0 Ω) between the above two points.


Do you have any recommend value for impedance between primary-side and secondary-side GND?



Would it cause some problem if we connect all GND with 0Ohm?


Best regards
