Imagine a simple PCB on high side is connecotr for 100A, in center switching MOSFET Rds On 1mOhm, and on low side PCB again connector for 100A to high current ground in power supply.
On board is too MCU with smal connecor +3,3V and low power grount to power supply.
The question is how to connect or not connect, or how to connect both groud?
I would welcome a reference to an app note in which the ground around the high current is being discussed.
