i dont know if this question fits to be in this category .
i am copying a circuit of a UPS that runs on external lead acid battery.
it has an ic on it...the manufacturer has removed the initials written on the ic , leaving me no way to find out which ic is this ????
is there any way i can find out which IC is this ???
Well, what are the specs on the circut you have. What is it rated for? I would assume that it is just a basic voltage regulator, it has 3 pins right? There are quite a few different kinds. It could be a LM317, LM338, LM7085C. They all have slightly different ratings so that would narrow it down.
I don't know if it is because the 14 pin chip is bigger and it caught all of your attention but it looks like also the 2 eight pins chips at the bottom have been grinded down.

Well I do believe you called it. Never noticed them and yes, I see nothing on them either. There is really no easy way to know or see what these chips are. Short of a schematic which obviously doesn't exist for the end user.
