We got a question from the customer about TPS22965-Q1.
Could you help us?

[Question]
How much is the OFF delay time? They want to know the typical and maximum value.

- Condition -
Vin=3.3V
Vbias=3.3V

Hi Tateo,

The OFF delay time can be calculated by using the equation below:

t_D,OFF = t_OFF - (t_FALL / 2)

In this case, for VBIAS=VIN=3.3V, turn off delay time is about 7us.

Thanks,

Hi, Thank you for your support. How much is the variation of t_D,OFF? They don't need guarantee. They will use it as refernce.

Best Regards,

Hi Tateo,

We have data for 3 units across temperature, and from -40C to 125C we saw less than 10% variation at VIN=VBIAS=3.3V. That should be a good reference point, but I would add some margin just to be safe.

Thanks,

Alek Kaknevicius
