Hi,
PG is open-drain output. Can you please comment when is the PG active? Is the PG active follow by the Vin applied? or Bias? or EN? Thank you.
Best regards,
Randy
Hi Randy,
In regards of which order you need for normal operations, assuming you met the requirements, you can refer to section 7.5.2 (see below) which says that the order in which you activate V_IN, V_BIAS, or V_EN would not cause any damage to the device.
However, PG is active once all three ( V_IN, V_BIAS, and V_EN) are all active and will go high when V_IT is about 90% of V_OUT. You can see an example of the PG behavior on Figure 6-22 on the data sheet (see below).
Hope this was helpful,
