Need help id'ing chip on a Dell g15 5515

[donnietr]

Hello all,
I have this dell g15 Ryzen Edition 5515. Board GDL56 LA-K453p. It had liquid damage when i bought it. Cleaned it up really well and then used thermal camera to see what got hot.
Found the power pdw1 and pdw2 under the graphics card were getting hot. Pdw2 was hottest, i had a similiar chip on another board so i put it on this board.
The other chip is now hot as well, which it was to begin with.
Thats the problem as i dont know what to call it, like is it a mosfat? or what?
I will attach a picture of both the boardlabel and of the area with the chips. The first one, pdw1 is the original chip. the pwd2 is the scavenged chip.
I would really appreciate what the name and company is so i can order new ones. thanks

You can use search engines - search AL00 on aliexpress, search for schematic, you find that similar schematic is here available which you can use as reference:

it is AOZ5332 "drmos"

First of all - why do you think that changing everything that is hot is the solution? What are the voltages on these coils, other coils? How does the mainboard react to power? etc

Thank You for the help!
I started by checking the first current sensor after the first and second mosfets. Showed a short on main power rail. I then checked all the other coils on the board.
I had no supplied power other than my tester. The power coils for the GPU both showed as shorted. I then did a complete visual inspection of the board and found water damage.
I cleaned the board with seltzer water after using 91% alcohol.
Then i used a thermal camera with the power plugged in and the 2nd drmos was totally red, and the first was glowing in the middle as a smaller ball.
I removed the second and when i supplied power and checked again the first was still glowing in the middle as before.
I can salvage another chip to replace the first drmos to see if that fixes the board but i really needed the name of it.
Thank You. Hope this shows what i did to your satisfaction.
