TPS2065D: TPS2065D 's FLT pin occur active low very short time when Vin rising

Part Number: TPS2065D

Hi team,

                 We have a urgent issue from TPS2065D and found there was a similar discussion in E2E. https://e2e.ti.com/support/interface/f/138/t/626890?tisearch=e2e-sitesearch&keymatch=TPS2065D

                  Could you please help us to solve it? Thanks! 

                 The Fault pin was pulled down to low during VIN was applied no matter EN pin is high (condition#1) or low (condition#2).

There is no device connecting to the USB port and the trace of USB_OC03- was disconnected. Please find the schematic below, thanks for your support!

Condition#1

Condition#2

Added Vout waveform: the period of low pulse is around 300us.
