Can anyone identify this component on logic board 820-00165-02 of MacBook Air A1466.

This is a logic board 820-00165-02 of MacBook Air A1466 2015. Touchpad and keyboard not working. I compared the board to another working one and there is a small THING written DV on it missing inside the red circle, it's connected to three keys on the touchpad connector. Does anyone know what that thing is? Thanks.

Thanks for the reply.
It has three legs, could it be Transistor?

I found a same thing right under this connector, photo attached. but don't know what is it.

Yup OK, that helps
it's probably that Q4800 which is a dual gate MOSFET
