SHUTDOWN_REQ and POWER_EN circuit

Hi,
I’ve made this circuit to drive POWER_EN based on SHUTDOWN_REQ, and it looks to me that it’ll work. But will it?

It’s based on the fact that there is an internal pullup on SHUTDOWN_REQ, and that the SN74LVC1G07DBVTG4 IC has an open drain output (Input L = Output L, Input H = Output Z).

Thanks for your help!

Hi, we don’t have suggestion on this kind of invalidated custom design. Please refer to the Power ON/OFF Logic page in P3449_B01 schematic in DLC and also refer to the power on/down sequence in Design Guide there.
