Help for identify BGA chip U24024 – Fujifilm X100F camera

[corrize]

Hello, on this camera I have an issue : the charging icon (battery symbol) keep permanently red and empty, even with different battery and full charged. I’m trying to identify components around the charging zone on the board, but I can’t find this one : the BGA chip with marking code :
U24024
708H33
I tryed RS, aliex, Farnell… combinations, marking code database : not found
Do you know what it is please ?
(Camera made in 2016).

No datasheet, but OZ8075PN is used in many different brands of camera:

As for how I found the other IC ...

FWIW, a Rohm BU24020GU has very similar markings (U24020) and VCSP85H2 (24 pin) package:

Therefore, I suspect you have a Rohm BU24024.

That match thanks, I was writing this chip could be probably proprietary chip but you found it. If you have a good database for find components, I want it please ?
So this chip is not power management.
I found another chip (see picture) getting hot (29 degree) when the battery present and charger plugged in. So probably power management chip.
But the same, I can’t find it on the web ?

OZ8070A is a USB Protection IC and Battery Charger in 20-pin QFN package by O2Micro. I guess OZ8075 would be similar.

Thanks for help and the link, it’s this chip. I know where to buy it now if I need.
I will open another thread for diagnose because the chip seems managing charge and end of charge fine. The issue is only the battery logo stuck.
