About ADP5080 Pin  Impedance

Question asked by Yuya on Nov 7, 2017
Latest reply on Nov 27, 2017 by Yuya


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"?
