Yes I believe that should be Co and Ro. In general I ignore those terms as Ro is always much greater than R3 and Co is very small (around 5pF).

I'm not 100% certain, but I think Ro is about 8 Mohm. I'll see if I can find out.

Thank you very much for your answer.

My customer select UVLO selection resistor.
Hysteresis current is 2.9μA(typ).
Would you teach hysteresis current are minimum number and maximum number?

I don't actually support that part directly. I do not have access to the characterization data. Perhaps someone from the automotive group can provide the answer.
