Can somebody help identify this IC

Hello everybody.

I have a JBL Boombox that doesn't turn on anymore so I proceeded to disassemble the speaker. After disassembly I measured the voltage on the battery and it was empty. Measured the input voltage from the charger and it was correct. 19.9 Volts and it was also present on the motherboard input power line. After separately charging the battery a little bit the sparker works and shows charging but it doesn't charge aka fake charging.

Upon examining the motherboard I found a chip a the charging circuit tha appears burnt. Cannot fin anything online about this chip. If anybody can assist me in finding more info or a seller for these chips I would appreciate it very mutch.
