Hi

it's from a MSI laptop mainboard, it says 4413/BA7G13
it is blown.. can you help me to identify that ic? the mainboard has
many similar chips 4468/BA7H95, 4805/BA7K13 there's a logo on the
chips with the letter A in a circle.

I have no idea what company it is. I just thought that these two threads should be linked.
 
Can't even figure out what company's logo that is, looked at numerous sites, this seems to be the best in my opinion:
**broken link removed**
 
I think all the leads on the right are connected together.
I think three of the leads on the left are connected together.
I think this is a SO-8 MOSFET.
Please check and see if my idea is right.
 
No where in the data sheet does it say what the part markings are.
30V 15A P-mosfet sounds about right for a lap-top power supply.

The pin out is right. I thought it was a N-FET.
 
It looks like the D and S connect to heavy power or ground planes. It also looks like it generates heat. (just looking at the PCB traces)
 
yes it is i found it too!! it's an alpha-omega component
a P channel FET http://www.datasheetcatalog.org/datasheets2/32/321875_1.pdf

i don't think it's for the power supply/charging cirquitry..the mainboard has alot similar ICs
one of them just now i found it's a dual fet..

the specific one that looks burned at the photo it's exactly above the VGA-out connector,
do you think it could be the cause for no signal from the VGA-out? (only S-video works)

now i need a replacement..any ideas for compatible chips?

if it's a MOSFET, then judging by the surrounding components, it's in a DC-DC converter. if so, i'm sure that it's not just the MOSFET that's blown. it's likely that there are other bad components around it as well as whatever device being supplied by the converter.
 
the only obvious problem with the functionality of the laptop is a broken display
and the VGA-out port which is not working, i can only use the S-video port

any opinions? also any ideas for equivalent replacement for the 4413 IC?

thank you
