Question about REGIN and REG25 of BQ27410

Dear TIer,

I have one question about BQ27410.

One of my customer is using BQ27410 as below. She is not using the integrated LDO, and using external LDO for power supply to BQ27410. Both REGIN and REG25 are opened (No connection)

Is there any problem? Is there any connection with REG25 internally?

Please confirm it.

Thanks and Regards.
