Hi team,

I have a customer with the below inquiry. Let me know your thoughts and thanks in advance!

"1) What is the max Turn on time at 5V? Datasheet only provides a typical number.

2) Turn on time is spec'd at Cload=0.1uF. What kind of impact to the turn on time if we use Cload=0.2uF

3) What is the max QOD resistance? Datasheet only provides a typical number"

Hoi Marco,

Please specify the variant. Also did you check the typical plots in the datasheet. Do they answer your questions?

Best Regards,
Arush

Hi Arush,

The variant we plan to use is TPS22916BLYFPR. I saw the typical plots, but I need to understand what the worst case timings can be so we can confirm some system level timing specs.

Regards,

Matt

Hi Matthew,

I am providing you some limits for reference purpose based on char data.

85us to 145us. This is for full temperature range.

If I remove -40C data, 135Ohms to 150 Ohms.

This data is only for your reference.
