Questions

Is there a KiCad symbol and footprint for the IP2326?

Yes. The symbol is EasyEDA_Cloud:IP2326 and the footprint EasyEDA_Cloud:VQFN-24_L4.0-W4.0-P0.50-BL-EP2.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the IP2326?

VQFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.

Where is the IP2326 datasheet?

INJOINIC publishes it: the Datasheet link on this page opens it.

Where can I order the IP2326?

JLCPCB lists it as part C2832094, with 19,778 in stock; the sellers' links on this page open their listings.

What can replace the IP2326?

Parts like it in the library: the BQ24616RGER by Texas Instruments and the LP6303QVF by LOWPOWER. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the IP2326?

11 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
