Hi team,


I would like to ask about the HW design of i.mx6solo around power supplies.

My customer is about to design their board with i.MX6Solo.

And they have a question around the power supply.

In their application, they want to secure the data in sd-card connected to i.MX6 in case of accidental loss of main power supply.

So, they think the following power supplies should be backed-up by external battery.









By the above back-up, they think i.MX6 can do the secure closing process of data files in sd-card before the unexpected main power loss.

As for the other power supplies of i.MX6, the supplied power will be lost immediately after the loss of main power of the board.

Is it possible to design the i.MX6 power supplies as above?

Can i.mx6 operate normally in such situation?

If there are other power supplies which should be backed-up than above, please let me know.
