Component Identification

[grimacelord]

Hello. I am working on a circuit board that is part of a motorized HDTV lift. The circuit board belongs to the controller component that tells the motor to either raise or lower the HDTV height.

The controller started sparking when the 29V power supply was attached and the green light on the power supply would go out as soon as it was plugged into the controller board. This indicated a shorted component and I was able to identify which component it is that is causing the short. When I remove this component, the short is cleared.

The problem is finding a replacement component. It appears to be a MOSFET, but searching it's imprint numbers/letters didn't come up with anything. I am not familiar with the component manufacturer logo on this component either, so I am not even sure who makes it. I will attach a few pictures and hopefully that is enough for someone to help me figure out what this component is or at the very least, what a good replacement would be.

Thank you.

Marking: D4013
GA3A11
Pin Count: 5 (4 leads and 1 plane)

*All 4 leads are independent of one another. They do not share continuity with any other pin. The large plane is connected to a coil inductor which is then connected to an identical component as this one on the other side of that inductor. I have attached close up pictures to show where this component went and the traces show how the pins are not interconnected with one another.

Maybe something from this series https://www.muhua.com.tw/en/product/mosfet/to252-4
Same as AOD609, AOD606 TO-252-4L (Complementary Enhancement Mode Field Effect Transistor)

That is what I would suggest as well, similar to SemiOne PE4025KC 40v, 16A, rds 18mΩ, there are many similar dual mosfets, this one is likely some Chinese brand.

I guess that is something simmilar to this (attach)... 4012... letters can varry from manufacture but numbers are close to wanted... you know for sure there is dual mosfet, and you can test it by transistor tester to confirm closest spec...

the inductor near it makes it look like a buck or boost convertor though.

Thank you for the replies everyone. I posted this exact question at numerous places so I could get as much exposure as possible. I figured I'd post some of the responses I have received at other places to see if it gets any ideas going about what I am working with here. I unfortunately haven't gotten any closer to figuring out what exactly this component is.

Here are some other responses (hopefully it helps)

First of all, we need to identify the manufacturer by the logo.
If we can't determine it, you need to draw a diagram and determine the functional purpose of this element.
Maybe I'm wrong, but I assume that this is a DC-DC Converter.
For example, like this:

I saw the inductor in close proximity and the part definitely gives me DC to DC Switching Regulator vibes.

I looked pretty hard to find that semiconductor logo and haven't been able to find anything yet.

Some sort of integrated half-bridge driver would be my guess. It appears that each of the two receive power and ground, with the output passing through a common-mode choke to the connector.

For what it's worth, when I was using ChatGPT to try and help me identify this, it was suggesting that it appeared to be a synchronous buck converter circuit…

Thank you guys so much for the help so far. Hopefully we can narrow this down!

EDIT: Also, the pin marked Pin #1 on the board where the component goes does appear to be GND if that helps.

Draw out the motor drive circuit, if it is used to control the motor and its direction, it is not likely a regulator ic.

But this is not an inductor, but rather a sound buzzer (polarity "+")

Mayby some sort of h-bridge to control way of rotation...
