Hi,

Generally, I would assume this chip is for mobile phone application. But I'm not just sure about your question. Is the chip supposedly a power management module? I can't seem to locate the datasheet for this one. If you can locate one, I believe that will answer your question.

I'm a bit confused. This is a mobile phone we are talking, right? Is the phone really OTG ready? Or it just gone dead after some time?

So I would assume in your general question, you want to replace the chip in the hopes that it would supply the 5V? I would suggest you let techshops have a lot at it.

Kevin is saying it as it is. If you have an android phone, there is an app that will tell you if the phone supports OTG.
If it does, and the hardware is faulty, it may not be repairable. The chip you are interested in is a BGA part, which means it is not replaceable,
cheers,
Richard
