Hello, on our design of the development kit, how can we replace the functionality of the MCU which handles the reset line, sleep, shutdown requests .etc?
Is using the following pins SLEEP/WAKE, SHUTDOWN_REQ, MOD_SLEEP optional?
Hi, it needs to design a logic circuit to handle the related signals to follow the power sequence as you can see in the Design guide.
Hi, can we get more details on what this logic circuit looks like?
Can you point out exactly what sequencing requirements need to be met?Is using the following pins SLEEP/WAKE, SHUTDOWN_REQ, MOD_SLEEP optional?
Did you read the Design Guide? There are clear info in it. The sequence is as below. For other signals than these, please refer to the Usage and Description of them in DG.

The SHUTDOWN_REQ is in the sequence.
Trumany, I would appreciate a little more attention regarding this issue.
If you read the notes underneath the image you sent above, you will see that SHUTDOWN_REQ is pulled up to VDD_IN and is not driven.
It is not driven during power on, but used in power off. You can get the full info in its usage description part.
