The fuse F1 on my brush gets blown when I turn it on. When replaced, I can charge the brush, all LED come on and U2 IC gets super hot. I assume this one drains a lot off current, tripping the fuse. I can’t find any information on what the IC is. On my toothbrush that IC has IU2FJ on it, another has IU2GG on it. I was looking for a 6 pin TSOP IU2 IC, but can’t find anything. I assume is some kind of power management IC.
Hi @kismayas , If you can’t find the compatible replacement component here’s an option to consider if your toothbrush is either of the two models listed. The following links may also provide some information that may be helpful regarding repairs and other parts etc, if the need arises in the future. link1 link2
To be honest with you need to get the schematic of it to get its part number You would be hoping that you get it from the IC on top but it seems that not all of it is there
You’re looking for an IC called MP9361DJ. I found it here: https://www.eevblog.com/forum/beginners/…
