About ADP5080 Pin  Impedance

Hi, 

My customers are evaluating using ADP 5080, but it does not start up even when EN is set to the high level. When VIN 5 is opened and EN is set to High, it is in a state to rise.
Also, when VIN5 was open, the boosted voltage was seen as same as CP.

 

From the above, I have a question.

 

① Is there a specification of impedance value between input pin and GND, BSTCP pin and input pin (VIN5 etc.)? I am

  also considering the possibility of a short circuit.

 

② If the impedance value of ① is not specified, what impedance can be confirmed, is there any indicator such as "abnormality"?

 

Best Regards

Yuya
