We plan to use batteries with the following charging specifications.
0℃≦Ta≦10℃ | 1.05A | ||
10℃<Ta≦45℃ | 1.505A |
When using BQ25616 or BQ25616J, is it better to support with ICHG = 1.05A of Hot / Cold Profile?
Please teach if there is a better way.

Hello,
As you may already know BQ25616(J) are both standalone devices, so it is not possible to adjust CC or CV values in the JEITA or Hot/Cold Profiles. The temperature windows can be changed by adjusting RT1 and RT2.
My suggestion is that you select BQ25616 and adjust T1 to be 10C and T3 to be 45C.
The resulting profile will be:
10℃<Ta≦45℃ 1.505A
The catch is that you will not be charging from 0℃≦Ta≦10℃.
Let me know if this is acceptable.
Best Regards,
Ricardo
