UCC21225A: The Max. data of Power-up UVLO delay to Output of UCC21225A

Part Number: UCC21225A

Dear sir,

https://www.ti.com/lit/ds/symlink/ucc21225a.pdf

In UCC21224A datasheet, Section 7.5 Power-up UVLO Delay to OUTPUt, it just lists out the typical data of Power-up UVLO Delay to OUTPUT ( 40uS/ 50uS), Now customer want to know the Max. one, can you share it with me?

Hi Jack,

Thanks for reaching out on E2E!

Often the ramp rate of VDD impacts the delay. So, with a specification like this, it is difficult to provide a maximum value that would extend to every customer scenario. With this in mind, we have found that most customers are content with just a typical specification.

Please let me know if there’s anything else I can assist with on this topic.

Best,

Hi Olivia,

Can you explain this Maximum value which extend to customer scenario? And you see, our competitor can provide it in their Datasheet.
