IC data for Ipod Mini

Hello Chieh, I saw that you have opened your Ipod mini. Could yhou please tell me what is the part number (whatever on top of the IC for IC11 (about 1 inch from bottom left as seen from the front of the Ipod) This ic is about 5mm square and have 16 pins, 4 on each sides. Somehow mine was toasted and I need to repair

Ok, I'll have to take my iPod apart to get you that information. From the picture below, would you circle the IC you need information for with a graphics software? That way I can be sure to get you the right one.

So how did you burn it out?

Here it is, I found out this morning that the chip should be LTC4055 USB Power Controller and Liion Charger.

Here is the photo of it in detail.. Toasted :(

I reckond the cable were shorted out while charging in my car. It was a long trip (6 hours) and the Ipod suddently died, and when I opened it this is what I found.

Parmin,

It looks like the surrounding components are also fried. Are you going to be able to replace all those parts?

Chieh,
I am a prototype contract designer/maker I made prototype for ppl with ideas but cannot realize them. I do work with SMD materials often and I have the equipment , so I would not have much trouble in replacing the chip.

The surrounding materials are the standard 0402 size capacitors and resistors. They are not fried, even if they are, I have them in my stock. The one I dont have is the chip. It is just my bad photography that show them as black parts :)

Although I think I know what the part number is, I cannot be sure. Based on the chip size, pin profile and rough tracing of the PCB, I think it is the LTC4055.

Did you open your Ipod? could you please either take a close up photo of the chip for me or if you could just write out the chip number for me please?

I see. I had the impression that you already know for sure what the chip is. I will take my iPod mini apart tonight and get you a picture and the chip designation.
