TPS74801: PG pullup before INPUT

user6519235

Part Number: TPS74801

Tool/software:

Hi,

I have a question about PG pullup timing of TPS74801/74901.
Is there any problem if pullup voltage of PG is applied before voltage is input to IN (pin1)?

PG (pin3) 3.3V pullup ⇒ IN (pin1) 3.3V input ⇒EN (pin5) 3.3V input

Best Regards,

Hey,

There is no problem with power the PG pullup before voltage is applied to the input.

Thanks,
