We consider the MC13892 different power source domains.
In application note AN3867 ( MC13892 Functional Pin Description),
it says that SW1/2/3/4IN and VINUSB2 and VINAUDIO and VINIOHI are connected to BP.
But we hope to connect these pins to the another power source other than the BP.
The BP is connected to "A power source".
The SW1/2/3/4IN and VINUSB2 and VINAUDIO and VINIOHI are connected to "B power source".
Is the MC13892 equivalent to this use method ?
Could you tell us the limit in the use ?
power up sequence related to BP and non-BP power source.
potential defference value between BP and non-BP power source.
