Hello. I have some questions of bq25600

1) Do I understand correctly that the VBUS pin can work as both a charging input and a boost OTG output?

2) If The PMID pin its out of boost converter and i use that for supply? What a max current drive this pin? 1.2A? And what in this pin when i plug adapter to VBUS pin?

3)What a maximum current of VSYS i can use?

Hi,

Both VBUS and PMID have boost output. The boost load current is up to 1.2A. In order to have the boost current limit, the boost load should be connected to VBUS.
The charger is a 3-A charger. It can handle up to 3A total current, i.e. the sum of the charging current and the system current. If there's no SYS load, the maximum charge current can be 3A. If there's no battery, the maximum system current can be 3A. Please note that the max input current limit is 2.4A, the charger current and system current may also be limited by the input power.

Thanks,

Ning.
