LM5170-Q1: nFault Signal

Hi engineers：

    I would like to ask question about the N_Fault signal, actually we already placed a 10-kΩ resistor from the SYNCOUT to AGND pin disables the fault check feature.

So theoretically the chip won't pull down this signal on its own, right?

    I want to ask what other circumstances the NFAULT signal will be pulled low by the LM5170 after powering on. Because this is the case in our actual testing.

Best regards,

Stella
