I need the model of these Gate Drivers

Sammy87 · Mar 15, 2022

Hello folks!
The card is a Zotac GTX 970 AMP Extreme Core Edition, and the high side MOSFETs failed after replacement.
I need the part number of these Gate Drivers so I searched for what is written on them, but I can't find the model/part number. They seem like electrical values rather than part numbers if I'm not mistaken. Any Ideas?

Reach out to @buildzoid which has a youtube channel called Actually Hardcore Overclocking and @Andy Shiekh for pcb repairs

Thank you so much.
BTW can I use NCP81062 instead?

It is pin compatible and the specs seem close enough so that should be ok.

Not my fault it if fails tho.

I think you may be mistaking me for someone else.

No need to worry about that

The card is already dead and I'm desperate to fix it by myself as I can't find somebody experienced enough where I live. Thanks a lot.

Low melting point solder may help with the removal.

I couldn't replace the MOSFET drivers yet, but I noticed something, which is while measuring the resistance of the shorted MOSFETs and then I short pin#1 (boot) and pin#2 (PWM) in the MOSFET driver, the short in the MOSFET is gone.
Can anyone help to determine if the MOSFET driver is faulty or something else?

I dont understand this type of problems but can i ask you something? I have the same card and bios chip died on me. I need the full bios and i see that you have no problems with bios. Can you put the bios chip on a reader and backup it? Thanks
