Hi all
Would you mind if we ask ISO7840?
<Question1>
How much is the capacitance value at each pins?
If you have these data, could you give us as the reference?
<Question2>
On the datasheet Figure.17 P20, we guess that "Input (Device Without Suffix F)" and "Input (Device With Suffix F)" are opposite.
Is it correct?
<Question3>
On the datasheet Figure.17 P20, about Enable, when VCCO connects to EN pin, EN current will be VCCO/1970.
Is it correct?
<Question4>
On the datasheet Figure.17 P20, about Output, there is description "20ohm".
Does it include FET Rds?
If no, how much is the FET Rds value?(For example; VOL=0.4V, IOL=2mA -> 200ohm)
Kind regards,
Hirotaka Matsumoto
