Battery Charging IC for Li-ion Battery Pack

[ejht]

Hi,

It might sound like a stupid question, but I am struggling with this.
I am looking for a battery charging IC that manages the battery requirements of my project, but I am not certain if I can use a one cell battery charger IC, such as the https://www.ti.com/product/BQ25300] [url]https://www.ti.com/product/BQ25300[/url], since the battery pack that I am looking are 3 cells in parallel (for example https://docs.rs-online.com/ae2f/0900766b8163e9c9.pdf).

I have been looking for an IC that handles multiple cells, but it is always refered to serial connection, and therefore the voltage stated for the configuration are higher than 4.7v (like the battery pack commented)

Thank you in advance

Yes, you can parallel the cells. (I did that with the BQ25895 in a recent project.) The important thing is for the cells to be well matched, so you want cells from the same lot, and never, ever replace them individually. In a purchased parallel pack like the one you showed, this is taken care of.
