Other Parts Discussed in Thread: LMZ31707, TPS74401
It is nice to know you here. My customer wants to use the TPS74701 PG signal to control LMZ31707 enable pin. However, 3.3V comes first and then12V, and then 1.5V. And they need 0.9V power on first and then 1.2V. They are afraid that before 1.5V power on, TPS74401 PG is on high impedance status, which will lead to 1.2V power on first. Could you please help check what is PG status if no power on TPS74701? Thanks.
