Hi Team,

My customer used TPS3123J12 and found the probelm in the datasheet.

They would like to know what the time slot from D to E showing in below pic. Is it 1us or other?

Thanks!

    Eggsy,

    TPS3123 WDI is an input, which means the user will control the pulses that occur there. The diagram is simply showing that as long as you introduce a rising or falling edge within the timeout period, a RESET will not occur. This should be set by your own manual WDI pulse.

    Thanks,

    Abhinav.
