TPS628502-Q1: Glitch on PG pin

Other Parts Discussed in Thread: TPS62811-Q1

Hello Expert,

I'd like to confirm about the risk of glitch on PG pin when I pulled-up PG pin to output of TPS62811-Q1 itself.

I think, PG pin's deglitch time is less than 1us and enable delay is approx. 135us.
So, I suppose that output won't become high as like as causing remarkable glitch even if PG is pulled-up output.
Is this understanding correct?

Best regards,

Hello Kazuki-san,

Yes, then it should not be a issue as device output will not be high before the EN delay time.

Why you are concerned about this glitch? Do you know the potental reason for this to happen?

Thanks,

Farheen
