What is the maximum VIN Voltage (on VIN pin) ?
the arduino docu says it's 6V, but the BQ24195L is rated for 17V, according to TI datasheet (to be found here: https://www.ti.com/product/BQ24195L#tech-docs ).
So: what is correct ? 6V or 17V ?
Welcome
Sorry I cannot give you a good answer, see what you are and another place 12V. Looking at the schematic I would say 17V but without an actual part that is a guess.
Thank you for your answer, but what would you look at, if you had "the actual part" ?
Sorry, I have no grounds to judge which datasheet is correct.
Perhaps the Arduino used the same datasheet from which I provided the data.
Which datasheet did you use ? can you provide a copy of the first few pages pages ?
Thank you.
There is one more thing: In "your" datasheet (which is actually the users guide) 6V is the recommended AC input voltage from AC adapter !
I w ould double-check the circuit against the schematic, as it states that changes can occur without notification. If everything matches, I would then verify the voltage ratings of the components.
If the components check out, I would gradually ramp up the voltage while monitoring the current. If you see a sudden jump, that likely indicates the limit. In most cases, the current should increase gradually.
The best approach is to follow the board’s specifications, as that is what the manufacturer guarantees. If you operate outside that range, you’re taking a risk. Since their values don’t appear to be consistent, I recommend contacting the manufacturer for clarification. If you do, let us know what they say!
Neither
The documentation says 5-7V

Anything else and you void the warranty
