Hi, I have been trying to wrap my head around why two mosfets are necessary in the circuit for the Addressable N-Mosfet Driver and not just one? What are the differences between the two and what is the meaning behind connecting them in that way?

Circuit: ... 1977644917

Mosfet 1 - RJU003N03 Datasheet: ... 003n03.pdf
Mosfet 2 - NTD5867NL Datasheet:

Thanks a lot.
