I am planning to use the bq21040 as it has a wide voltage input from 4.5V to 28V.
Ideally, Vin will always be 5V, but there could be a possibility that Vin be solar cells rated between 12v to 24V.
The PCB have a USB connector connected to the bq21040.
Are there any confederation to keep in mind when Solar panel is connected to the micro USB connector using a custom cable and outputting 12V-24V?
The bq21040 will be configured to output 500mA to 800mA.
Please note , the USB will not be connected to any device such as a PC, when connected to a solar panel.
