Hardware 2DS ic chio charger

[Mauroz]

Hello,i have old 2ds that not charge battery.If i put original nintendo charger in a port charger have a orange led for 2/3 second and after led turn off.I have checked charged port, battery and charger too with other 2ds and this component are ok.I have checked too F1 and F2 and are OK, and too induttance EM1 is ok. I think that problem is causated by Ic charger, but i don' know exaclty model i need to buy for replace it.

In my 2ds ic is labeled CKP TI 351 AD35 and have 4 pin every side. I have watched ebay aliexpress, but don' find the same. Where i can find it?

Have you tried charging a different battery? Maybe your battery needs to be replaced because it no longer takes or holds a charge?

You'll need hot air or reflow work station to desolder the IC charging chip.

From one of the other threads, I linked:

The part number for this chip made by Texas Instruments is BQ24072. Here's a quick search from digikey:

• [DigiKey.com] Search Results "BQ24072"

As for which exact option you should choose of the several listed there, I don't believe there's a wrong pick if they all have the same specs. The additional trailing tags in the part number probably refer to slight revisions, production batches, and packaging.

Since you live in Italy, it might be better or faster to buy that IC chip from Mouser (UK branch). This is another online retailer that specializes in electronic repair parts.

Today i came across same issue, BQ24072 IC replacement helped to solve this problem. (I got mine BQ from broken JoyCon)
Main Reason why this issue appear (learned by own mistakes) - wrong battery polarity.

Thanks how joycon?Switch Nintendo? I understand youe experience, but in the 2ds or 3ds i think that is almost impossible insert a battery with polarity wrong

Everything possible when you work only with motherboard =) at 4am at night.... ahahha...
Yes, fortunately for us they used same chip in the Nintendo Switch Joy-Cons, and same battery just in different format.

yes work only with motherboard may be, but i have found IC charger damaged in a 2ds never opened

Where is the IC on the 2ds motherboard

I also reversed my polarity. Both of my fuses are good so I am guessing it is the IC. Where is it on the 2ds board and is there a way I can test it to see if it needs to be replaced?
