Hi everybody,
I just bought two bq24210 IC for my new project, a wireless sensor powered by a solar panel with a backup battery. My problem is that I got confuse between the the VBUS volatge range (0-18V) and the VBUS operating voltage range (0-7V) restricted by the OVP (over voltage protection).
My solar panel is 9V and 0.3A. So my question is, can I use it directly with the bq24210 chip or should I put a buck DC-DC between them in order to provide a maximum 7V input on VBUS?
Thank you very much,
Nico
