I saw what you mentioned. As you said, it's input is the concern. I would typically work in 12v range, but transient of up to 30 is possible.
Looks like what the TPS3806 is doing internally, though, is similar to what I am trying to do with TPS3701…
Kazuya,
I think you have a few options here.
Option 1:
TPS3808 is a programmable and adjustable supervisor http://www.ti.com/lit/ds/symlink/tps3808.pdf
And using a technique outlined in this app note you can add hysteresis. http://www.ti.com/lit/an/slva360…
Hi Graham,
Thank you for the explanation! Please take a look at TPS3806. This family enables you to select the threshold that you would like /RSTSENSE to go low and a higher threshold where you allow it to go high again.
Very Respectfully,
Ryan
