I have an SMD 8 pins micro IC(2mm x 3mm) that I would like to find out what It is so I can replace it. This component in in the power section of a CARDO Scala Rider G4 unit and the marking on the IC is "AAL110 5R" with no logos. The location on board is U603. CARDO have informed me that the unit are no longer being made and no other information are imposible to find. Since the rest of the unit is working fine I just can't charge or use the USB. Any ideas? I have search the MAXIM site whom has most AAL markings belong on their IC, but I just can't narrow it down to the part number.
