    Hello,

    You must set Settings:Manufacturing:Mfg Status Init[FET_EN] bit to one in the OTP. After OTP has been programmed, then your device can operate autonomously.

    Make sure FET Options[FET_CTRL_EN] is defaulted to 1 and FET Options[FET_INIT_OFF] is defaulted to 0 as well.

    Please let me know if this solves your issue.

    Regards,
