ALLDOCUBE iwork 10 pro Tablet charging current burned IC

[stupsy]

Hello ...i am new here. I have an ALLDOCUBE iwork 10 pro tablet. By mistake i put a powerbank to charge the tablet. The tablet needs 5v. But the power bank switched automatically to output 12 v. and failed to start.

and also......my sdcard was inside got burnt.....and at times the touchscreen fails to work.....(2 out of 10)

I opened it up. one IC is hot .......(picture attached):
-------------------------------------------------------------
i have removed the IC....everything working fine again...CHARGING OK.... but i doubt the ic has an important role to play such as overcharging protection etc.

--------------------------------------------------------------

ANYONE PLEASE CAN TELL ME WHAT IS THE IC? I CANNOT FIND ON THE WEB....
ANY ALTERNATIVE?

I think it is PS7516. Available on AliExpress.

The 'D6G' markings are the same.

Confirm the markings and part number with the vendor before buying.

Thank you friend.....

Does this ic has anything to do with the touchscreen....coz at times after 5-10 minutes use...tge touchscreen does not respond. Unless i press the power button once (screensaver)and pressed again...(wake)
