Hi guys my UTI690B dead during standard charging battery…
Just opened it and found I think is a transistor is burned. Can you help me please with identifying replacement for this component? Thx.

Welcome to the Technical Forum. I am not sure on this one. I looked at part number SI3401AHE3-TP, but it does not seem like their part marking format. Here is the link: https://www.digikey.com/en/products/detail/micro-commercial-co/SI3401AHE3-TP/16032728

I think on this one we will see if anyone else has a better option as I am not sure if I am correct. This is a forum post so others do watch and offer input.
