Part Number: TPS386000-Q1

Hi TI-team

My customer want to know Delay below.

The data sheet did not mention this delay.

Please tell me how long this delay will be.

Please tell me the delay time when changing the SENSE voltage from 420mV to 370mV at the slew rate of 200µs.

I previously posted the same question but you didn't answer it so I posted a new one.

Best Regards,

Hi Koji-san,

I now understand your question better. You are looking for a propagation delay/detection delay spec. We currently do not list this in the datasheet (it is almost instant) as shown here.

Thanks,
Abhinav.

Hi Abhinav-san

Thank you for quick response.

>it is almost instant

How long is the above ?

Is it 1 μs or less ?

Is there no calculation method ?

Best Regards,

Koji Hayashi

Hi Abhinav-san

My customer's evaluation result was 43.3 μs.

Is this a reasonable result ?

I'd like to know the maximum value as well, since it's not on the data sheet.

I would like an answer as soon as possible.

Best Regards,

Koji Hayashi

Hi Koji-san,

I will reach out to design regarding the range of these values, but since we do not guarantee on the datasheet, they will not be guaranteed values. The range of 40 us seems appropriate, however.

Thanks,
Abhinav.
