Other Parts Discussed in Thread: BQ25798, BQ24210, BQ24250
Hi
I am re-evaluating a design I did last year which used ST parts. Now I am aiming to migrate the design to TI BQ25570
The BQ25570 combines atleast two circuits into 1
I am seeking your feedback on to its suitability
I am using a 1.3W solar panel to charge a 21700 size battery
The battery spec is 3.6v 4000mAh with charge voltage 4.2V
The solar panel is Vmp 4.4V Imp 295mA Isc 320mA
In the BQ25570 datasheet I see Cycle by cycle current limit of charger is typically 230mA
Which fits in nicely given the variability of solar energy across the year( I'm in New Zealand)
Is the BQ25570 best fit ?
I am considering also BQ25540 but not so sure its the best fit
We looking at volumes 1000per year at least
You recommendations are welcome especially given I in time critical design phase
