Comparing power-up sequence from TX2 to Orin NX

Hey,

I’m trying to update our computer product from the TX2 to Orin NX by modifying our design. I’m beginning with the power-up sequence and I noticed a big difference between the two in terms of the circuit design. TX2 had a bunch of AND gates such as this:

, but the Orin seems to have a power button now to toggle the power_enable pin instead using an MCU such as this:

My questions are the new power button is that intended to replace the old on/off logic from the TX2? Could the old on/off logic form the TX2 work just as well for the Orin, or is there some new consideration I may be missing?

Thank you.

If you do not want to use the button MCU, you could replace it with discrete logic as used in previous carrier board designs.
