Hello all.
I don't know much about circuits and parts but here's my situation;
I'm doing a review on an electronic device and part of it is a USB charger containing a 10430 Li-Ion battery (3.6V AAA size). The previous model didn't have any overcharge protection built in so you can imagine that was quite a dangerous situation. I know the usual strict rules on Li-Ion charging and how dangerous it can be to overcharge them so I've had contact with the manufacturer and told them they needed to go back to the drawing board and make it save.
Now I've received the new model but looking at the inside I can hardly imagine that this is a state of the art Li-Ion charger![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Anyway, all it has to do is stop charging when it reaches 4.3 volts (at most) so I was wondering if anyone can tell me if this circuit can do that. Aside from the 2 resistor and 1 capacitor I don't know what the U1 part is. There's no printing on it and it's got 5 contact points but as far as I can see only 3 of them are used (upper 2 and middle lower).
Any help would really be appreciated.
