Hi team,

Could you advise if there is any specific recovery operation is required after brown out condition?

Brown out means the supply voltage drops momentary and recovered to normal supply voltage in a short period.

Hi Shinji,

For Brown-out condition I would expect that RSTN pin is toggled to recover device performance after a proper reset. In this case if USB 2 HS enumeration does not happen after reset boosting will not be enabled again after reset.

Hi Malik,

Do you mean that USB2 HS enumeration is required after RSTN toggle?
