How does ADM693 shift the watchdog-timeout to?

Dear Sir/Madam,

As for your ADM693, our customer asked the following question to us.

I could not catch the answer on your datasheet.

So please let me know your comment.

The watchdog timeout period is showed min 1sec to max 2.25sec when VCC = 5V, TA = +25C.

Q-1

If VCC is shifted to 4.5V or 5.5V, then how should we think this value shifting?

eg; when 4.5V, shift min 0.9sec to max 2.15sec ? Otherwise same value?

Q-2

If TA is shifted to 0 to 70C, then how should we thinkthis value shifting?

eg; when around temp=0C, shift min 0.9sec to max 2.15sec ? Otherwise same value?

Please let me know the trend when the above conditions.

My expected reply as following chart if you have.

Thanks Kaos

  • Hi Kaos,

    The data was averaged from three parts.

    As i mentioned before, it grantee a limit around the spec, Yield Analysis need to be performed which we are not in the position to carry out for this part.

    Please understand this part is 20 years old and the design data is no longer accessible.

    If your customer wants a well defined watchdog timeout range, i would recommend the use of ADM8693, which is pin to pin compatible with ADM693.
