Wanted busted cardo scala rider G4 for parts

Post by Caceci » Fri Oct 10, 2014 1:56 pm

I need to fix one of my scala rider G4 unit. A chip inside fried and now it will not recharge on it's own. The marking on the chip is "AAL110 5R" it is very small. If anyone can identify who is making this part would be greatly appreciated. I have tried every avenue possible. Maxim was the closest I came to, but they replied that they do not make the chip :( . Tried Cardo they do not give this type of support :( . So I am left with the hope to catch a busted one for parts where maybe with two or three unit I can make one work.

I had a quick poke around, the only reference I found was another posting you made on Digikey. :)

If it's in the psu section of the circuit, my first best guess would be a regulator to monitor the voltage in the (what I assume is) Li-Ion battery, to avoid overcharging and taper charging correctly. Also perhaps to regulate current draw out of the battery, to avoid thermal runaway inside the cell(s)?
