The continuity check on USB OTG charge controller was not ok(Very low impedance found 99ohm between VCC to GND)
Due to failure of USB OTG controller, fault pin status was always pulled low which makes the indication of failure in IC.
Check the below waveform taken from issue USB OTG IC.
This is a customer reported issue and the Question is what causes the failure of the USB OTG Controller.
Need the complete analysis on the same.
