IC Data Sheet
« on: December 01, 2018, 07:49:37 AM »
I search for a data sheet for a IC for my battery charge this is a JRC MG017C but I did not have much luck to get it.
So, I need some help from my colleagues on this forum, I will appreciate any information from you.

JRC logo it does bring memories to me from the far past 1990~1995.

One good reason not finding what you are looking for this is because this product now considered as obsolete and the maker is not alive (no website).
Therefore internet is empty from such information.

I can hardly recognize this charger, what this is used for ?   (looks like Ni-CD cordless tool charger base with separate DC power block )

Thank you very much for your answer.
I think this charger is from a portable radio station, it's a friend who asked me to fix it.
He powered it from a solar panel and probably did not check its output voltage, it may be over-powered by a higher voltage.

I would measure (check) all four mini diodes and Q021

DC input delivers power to several components (PC trace of positive).
Some chargers does not demonstrate sign of life with out device hooked at the charging pads,  get also the radio device in your hand for your testing application.
