Hi TI-team
My customer want to know RESET(Tw) delay time.
What is the delay time under the following conditions ?
Apply 370mV to the SENSE pin and set it to 420mV at a slew rate of 200μs.

Hi Koji-san,
The spec (tw) you are mentioning is related to the minimum pulse width required to detect a pulse on the device. This must be 4us. Do you mean delay time (td)?
Thanks,
Abhinav.
Hi Abhinav-san
Thank you for quick response.
Sorry, I had a misunderstanding.
They want to know the delay time.(Not tD RESETn or RESETn delay time :20ms or 300ms)
The red circles in the figure below.
What is the delay time under the following conditions ?
Apply 370mV to the SENSE pin and set it to 420mV at a slew rate of 200μs.
Also, there is no mention of this delay in the data sheet.
Where can I find it ?
(The slew rate does not have to be 200 μs.)

Hi Abhinav-san
My customer is waiting for the answers to these questions.

Hi Abhinav-san
I summarize the questions.
1.When RESETB is high (during normal operation), what is the time from when SENSE falls below VIT to when RESETB goes low ?
2.Apply 420mV to the SENSE pin and set it to 370mV with a 200μs slew rate.
Time from VIT to RESETB:H⇒L at this time. (Time to detect the same as No.1)
Could you answer ?
Please tell me if you have any questions.

Koji-san,
We are working on answering these questions specifically. For the TPS386000-Q1, we do not have this propagation delay characterized in the datasheet. As such, I have reached out to designers for more info. We need to wait on their response to see if they have further insight.
Thanks,
Abhinav.
