Got myself into a bit of face-meet-palm situation while wiring a +5v power cable for my SJ4000 camera. Reverse polarity did its thing.
There is no obvious damage, blown/black bits but i suspect i have blown UN8HX charging IC.
I cant find a replacement for it in UK and trying to get it somewhere that doesnt involve slow boat from china or 30gbp delivery charge for a grain of sand.
The camera works just fine when hooked up to usb cable, which is also charging port, but charging capability is gone.

Alternately i might replace it with analogous replacement if i knew what they were.

Maybe someone here (uk based) might spare one IC, i'll pay the part and shipping of course.

 

I googled the part number to find out what it was. Several other part numbers were listed as equivalents if that helps:

UN8HX Single 4.2V 500mA small size Lithium charge management IC Also supplied as 2YL6, H1JC, 54B4, G5242

 

The only equivalent i found on ebay was 2YL6, 7gbp delivered. ghhhhhh...

Where do people buy ic's in small quantities to not be ripped off ?

 

Could it be a ripoff of this chip? http://www.linear.com/product/LTC4054-4.2

 

Slow boat from china it is. Shopping for discreete components is apparently a nightmare...

And what a hell is with delivery charges in uk ? 12 pounds to deliver a single smd component ?

 

Found it on Ebay uk, £4.99 Surrey...

Have you tried digikey or mouser and selecting the USPS shipping option? The USPS priority mail rates for international are excellent.

Royal mail impose a racketeering 'handling charge' to collect import duty.

For small value orders, some Chinese suppliers put "gift" on the declaration - no duty/no handling charge.

There is probably a value threshold for duty to be applicable.

Plus delivery = 7 quid. nope.

Bought 5x LTC4054 for a little over 2 dollars from somewhere in china. As i said - slow boat from china. And then people complain that everything is made in china.
