Can you please help us with our customer's inquiry below?
We are currently designing a portable power bank using the BQ25895RTWR.
The charging current to other devices is supplied from the PMID of BQ25895RTWR, but we would like to know about the overcurrent limitation of the PMID.
I understand that according to the datasheet, the maximum current that PMID can output is 2.4A when the capacitor connected to the PMID pin is 40uF and 3.1A when the capacitor is 60uF.
Qestion1: Is it possible to interpret this 2.4A or 3.1A value as the limit for the output current of the PMID pin?
Question2:Currently our circuit has 47uF connected to the PMID pin. In this circuit, in case the PMID pin is shorted for some reason, what is the maximum approximate short-circuit current that will flow out of the PMID pin?
Our internal other circuit designer explained to me that the overcurrent protection activates at 2.4A, but I understand that is a misinterpretation and would like to know how it actually works.
