DRV8350: nfault problem

Tool/software:

Dear. Ti team

we are currently using the DRV8350RH

We have encountered a slight issue where we change the enable pin of the gate driver IC from low to high, the nfault pin drops from high to low and then back to high, causing an error in the MCU that recieves the nfault input.

The nfault pin drops approximately 5V level to about 2V within about 1us.

since the nFault pin is low active, it has been connected to gate driver output voltage of 5V through a pull-up resistor of 10kohm.

additionally, there is no voltage drop in the gate driver output voltage of 5V when changing the enable pin from low to high.

please help us with how to resolve this issue.

Best regards
