LM5050-1: Wondering if Vgs voltage is too low

Part Number:LM5050-1

Hi expert,

My customer uses LM5050-1 in their USB-C / Adapter Oring application. And they tested on their mother board and result is shown below. We can know Vgs(Vgate-Vin) would be 3V maximum. We are wondering if it is too low causes Rdson too high. Or this test result makes sense, could you please kindly let us know why it would be?

They tested with below schematic without the red circle resistor. Another question is if we can place pull down resistor at GATE pin? Thanks a lot!!

Best regards,

Ann Lien
