Other Parts Discussed in Thread: BQ25700A

Hi,

for my project, I need to implement an accumulator and a USB cable power supply.

What kind of components can I start to evaluate?
I do not have any system specifications. My question is generic.

Thanks for your collaboration.

Davide,

I'm not sure what you mean with an accumulator. This is not something that would be supported by this Forum. However, we are happy to help with any USB related questions you may have.

Thanks,
Eric

Hi Eric,
I'm studying the data sheet of this component BQ25700A - Battery Charge Controller.
This aspect is not clear to me: if I have a rechargeable battery of 1200 mAh, how long does the bq25700a charge it?
The bq25700a how long does it charge 100%?

David,

The battery specification might be a better reference. General speaking, the battery charging time is 2-3 hours if 1C rate is used. 1C rate is 1200mA for 1200mAh battery. Please make sure to check the battery specification about the maximum allowed charging current.
