How to ID small packages stripped from a board?
« on: July 07, 2015, 07:44:14 pm »
I disassembled a battery bank (since the controller board is not working properly, and missing a chip anyway) and here are some chips that I cannot ID. Hope you guys can give me some pointers:

* "KL4" SOT-23-3
* "A152" SOT-23-5
* "CD=E24" SOT-23-5
* "F3K" or "F3KI" SOT-23-3
* "GRJH" SOT-23-6
* "A13HB" SOT-23-3
* "HXN-AP" SO-8 with thermal pad
* "8205A Z1J05" wide-body TSSOP-8
* "TQ7604 42CHG" TSSOP-8 with thermal pad (difficult to read under a magnifying glass even with 20/20 vision)

this http://www.marsport.org.uk/smd/mainframe.htm or google or ... bad luck.


the 7604 is probably this: http://www.mouser.com/ds/2/200/irf7604-298600.pdf
Maybe 30 seconds of google. Have you tried yourself?


You haven't done your homework. UTFG please!

I've just tried another one (KL4) and IDed it on the first try: http://www.farnell.com/datasheets/1317753.pdf

You seriously couldn't ID a 8205A? :o Agree with the poster above, do some more Googling first and come back with the ones you can't find...

Googling those SOT-23 packages and the "HXN" frustrated me out as those always turned out fruitless, either flat out no relevant result or the packaging does not match the one I have at hand. If I should Google it then how?

Nope the "8205A" is a TSSOP-8 package and obviously the one from the linked datasheet is not one. I asked here because Google turned out fruitless.

Are you seriously telling me you didn't notice any of these!? :palm: :palm: :palm:

I did notice a few of them but none of them mentioned the exposed pad. Like the one above you, wrong package!  :palm:
