Hi Team,
My customer would like to use 4.5V/per cell on their 4S system(NB) so Vbat will up to 18V.
As far as I know, hybrid power boost charger cannot meet customer's requirement because Vbat will higher than adapter voltage in worst case.
Therefore, we are considering to buck-boost charger. But I am not sure BQ2572x can meet customer application or need to use 5S solution BQ2573x?
Please let me know if your have any suggestion. Thank you.
Best regards,
Hardy
