USB/Solar charger selection

Other Parts Discussed in Thread: BQ25570, BQ24650, BQ24210

Hi,

I need a charger that can charge a 7800mAh,3.6V Li-Ion. It will charge the battery from USB 5V or a solar panel 6V. Ideally it would have a different pin for the load that will draw up to 1A. I looked into the BQ25570 but it seems to extract some miliwatts that are not enough for my application. Do you have a chip that could do the job?

Thanks,

Adina

    The bq25570 is only going to support an out put current of 100 mA and the max input of 5.1V.  You can take a look at the bq24210 or the bq24650 both of them has higher input voltage limit. However, you will still need a separate charger to charge your battery through USB.
