Hi,

Could you tell me the standard variation of Rising edge delay of IRQ to rising edge of PRESN(2us(typ) ?

My customer require to check the maximum time from stopping WDT to RESN goes Low on the safety relevant.

Best Regards,

    Hello Kuramochi-san,

    Do you want to know the variation of "Rising edge delay of IRQ to rising edge of PRESN" or do you want to know the "maximum time from stopping WDT to RESN goes Low"

    Both are different and I did not understand your question fully.

    Rising edge delay of IRQ to rising edge of PRESN is really small and we dont have the min/max data for this parameter. Can you please let me know why customers wants to know this variation and how they plan to use this data in their analysis?

    Maximum time from stopping WDT to RESN goes Low: RESN will go down if WD pulse is not detected during its window time (Watchdog window time = 20ms-typ, 18ms-min, 22ms-max).

    Regards,
