    This issue has been identified.

    Customer has a brownout circiut which includes a schottky diode. The forward voltage of the schottky diode increased with decreasing tempeature causing the V33 drops below 2.9V resutling in a brownout.

    It is a good pratice to chose a chottky diode with a small forward voltage to avoid triggering brownout.
    thanks
