Hello,

On page 90, it specifies leakage current but I want input current that required to drive PWRONRSTn pin :)

Thanks and regards

This is an LVCMOS input. What other current value do you expect?

Hello,

But leakage dc current is given, I want minimum current that required to drive PWRONRSTn pin? leakage current and driving current is same?

Can you please describe what is the reason you are asking this question? What are you using to drive the reset input?

Hello,

I am using TPS-3823 Reset IC to drive PWRONRSTn Pin. It's Output current is 1.2mA. So I just want to know that whether this current is sufficient to drive PWRONRSTn pin.

Thanks and regards,

More than sufficient. PWRONRSTn will draw in the range of a few microamps.
