BQ24278

Other Parts Discussed in Thread: BQ24278

Hi Jeff,

This is the third and final, hopefully, question about BQ24278. As I said before, I'll use the chip just for charging Li-Ion battery. I've asked how are the connections if system load is not present. I'm asking now how your BQ24278 works in the absence of system load, for example DPM feature of it? I preferred BQ24278 for 2.5A charge current, and completed the design according to your reecommendations. Is there any other point that I should take into account?

Thanks.

    The VIN(DPM) feature, which reduces input current limit if the input voltage starts to droop, works the same with or without system load. The DPPM feature, which scales back charge current if the system needs more load, is not applicable.
