Hi,
I need a datasheet (or any info) about an 8 pin surface mount chip. It
has the markings 9435M and 425212 on it - i'm hoping it's some kind of
5V reg but can't be sure.
TIA
Dave

But this is a russian website!
Maybe you have more markings, don´t you? Like SAA......

Made by Xicor?

Apparently various firms, PDF links provided. All apparently useless
though. They don't go anywhere. It's not enough that I don't read Chinese,
there isn't even a hint of a PDF file in the source code.

Okay, i found the source..^^
http://www.hqew.com/en/buyer/inventory/search.asp?keyword=9435M&imageField.x=62&imageField.y=8
It is a SOP-8 SMD IC and will support by a lot of companies.
And here is the datasheet. you have to switch : English..^^

Okay. maybe you may help me at my problem....see posting pls.

Well, you got a tad further than I did, you found a PDF at that address.

Did you look at it though?

That's for some LSI with lots of pins, it's not the little SOP-8 thinger in
that picture the first poster showed us.

Try 9435M instead of 9435/D...

......not 1st PDF.....get the second it´s called VMOS 30V / 6A.......

I see only one PDF there..
I used this link that you posted:
http://www.hqew.com/en/DataSheet/detail.asp?pdid=130024

That site doesn't give up its secrets easily though, it might give us
different stuff depending on where we access it from, for one thing.

......not really i got 3 .

Well, it was your link I followed...
But sure, your new one gets three. (And neither 2 or 3 seem to have a
PDF anyway). I'm not sure that P-FET is the right one, but it might be. The
IC form is right, but 9453M might be a very different thing.

I did find a link (posted earlier) suggesting Xicor as one maker, so
writing to them might get something specific to that exact code of 9453M.

To continue with Google I think it is best to establish some makers for
that exact device code before looking for data sheets anyway, the only
reason I tried to grab one is because it appeared to be offered by that
hqew.com site but I couldn't find one. So far neither of us had found one
there, and there probably isn't one.

The close proximity to an inductor & rectifier might suggest a switching psu
controller.

That's a clue - I think it might be a dual power MOSFET.

Just trust! It is a P-FET because the pictures show a VCO PCB !
Otherwise ......open a new .........posting for help and beginn a new

The 9435M is used in this schematic.........

That's a MOSFET of some description. Pins 1-3 and 5-8 are wired together.
Industry standard pinout is:
Pins 1-3 Source
Pin 4 Gate
Pins 5-8 Drain

9435M is just the main part number, the prefix has been dropped. Assume for a
moment it is a MOSFET - we Google for "9435M MOSFET". One of the results is
<http://www.diodes.com/products/appnote/pdfs/power/sw_reg/ANP004_AP2001.pdf>.
Page 7 in fact. That gives us the part numbers "CEM9435" and "AP9435M".

So we Google again for "AP9435M" and we find
<http://www.jlink.com.tw/Datasheet/APOWER/AP9435M.pdf>, which is a datasheet
for the AP9435M.

That any help?
