Identify microchip?

There is a motorcycle headset, one day it smoked when charged from the cigarette lighter.
As a result, it stopped charging.
Photo of the assembled headset:

Disassembled photo (On the photo is a working headset)

On the one that was smoking, this mikruha was swollen.

Google didn’t help by marking, can anyone help identify the part?

This is a lithium battery controller. Housing TSSOP-8. Try looking for such microcircuits in different catalogs and see which one is similar to yours in terms of operating parameters (battery type, voltage, current), pinout and strapping.
Maybe it's something from fortune's chips: FS8820, FS3332 or DW01MC ( http://www.ic-fortune.com/eng/new_product1_1.asp )
As far as I can see, the pinout is suitable: 1 and 2 pins - ground , 3 and 4 together, 6 and 7 also together.

Maybe this will help you . There are quite a few markings for SMD components.
