HI ARUSH

thank you for your reply

I would like to know the maximum and minimum values ​​of retry time.

How much capacitor value do I need to set to set to 3 seconds?

thank you.

    Hi Kim,

    We can continue our discussion here. Do you want 3second itimer or retry delay?

    Best Regards,
    Arush

    Hi Kim,

    You will have to keep around 62.5nF cap at RTRY_DLY for 3s retry delay.

    HI ARUSH

    Thank you for your reply.

    I will ask the my assistant SHIN to close the previous discussion.(because i can't see that resolved button in previous discussion)

    i want to know Maximum, minimum about retry time&capacitance

    is there no limit?

    i will try it 62.5nF 

    thank you.

    Hi Kim,

    Yes, we don't have any min or max for retry time delay capacitor. You can evaluate the device with the above-mentioned cap value. In general, the operational principle is simple, small current source charge the cap. For large cap, we get slower dv/dt (charge rate) and takes longer to hit the desired voltage threshold.

    Device may cause some issue if you choose to use very large caps. You will have to evaluate the device with them. 3s delay should be fine (I think I have done/seen something similar in past).

    Please reply here if any follow up question or click resolved if none.

    Best Regards,
