Hi,
Customer is trying to use TPS65400 under the following conditions.
Is high impedance when PG is VDD is not?
What is the timing of the startup, which can determine the PG to Low.

Hi Yusuke,
1. Yes, PGOOD is high impendance when it goes to high.
2. PGOOD goes to low when VDDA voltage goes up to 3V.
Hi Daniel,
Thank you for your a support.
For example,
Does PGOOD1 become Low at time of VDDA=3V and EN1=Low?
