Hi,
I was wondering about kelvin-source mosfets.
Is kelvin-source pin and the power source pin have mechanical connection or they isolated?
What happened if i connect them each other a same ground ? or should i isolated kelvin-source and power-source connection? Must i need a isolated gate driver?
Thanks for replies.

Hello sarsuk,
The kelvin source MOSFETs offer two source pins.
Both of these are connected to the source pad, therefore they are not isolated from each other.
As shown in the image above, the kelvin source is connected to the source pad and it has its own wire.
This pin allows bypassing the parasitic inductance of the traditional source pin.
You can safely connect them together. There is no isolation needed.
However, you will lose the benefits of having a kelvin-source package.
Best regards,
Pablo
