Some questions regarding the PMIC nPM1300

[Fconta]

I have some initial questions regarding the nPM1300 :) :

- It is possible to download the nPM1300 datasheet as a PDF file instead of viewing it online?

- Regarding VBUS and VBUSOUT pins: Its this just a pass through or is something else between these two pins?

   On other words, with fast chargers able to provide more than 5V, is VBUSOUT over 5V also?

- In following up, does the nPM1300 negociates a higher input voltage than 5V?

- It is a bit unclear to me if VSYS follows VBUS voltage or not.

- For connecting other power source, such as a solar panel, VBUS will still be the main power input pin?

- Lipo protection must be external, right?

- And finally I'm evaluating using a complete module such as those provided by uBlox or Fanstel. No issues with these, right :) ?

Thanks for your help.

Hi Jared,

A buck converter being at 5V just as USB.

Hi,

We have not tested this, since the nPM1300 is meant to supplied by an AC wall adapter or a USB port. CC1 and CC2 needs to be connected since they will be used for USB port detection. I wouldn't recommend it, since it's outside it's intended use case, but a possibility might be to connect the CC1 and CC2 pins to the MCUs GPIOs to emulate the CC1 and CC2.

If you have any more questions, then please create a new ticket.

Thank you Jared,

I will keep design as is(connected) and figure out if there will be actually any issue.
