Questions

Is there a KiCad symbol and footprint for the L6472H?

Yes. The symbol is EasyEDA_Cloud:L6472H and the footprint EasyEDA_Cloud:HTSSOP-28_L9.8-W4.5-P0.65-LS6.6-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6472H?

HTSSOP-28-EP-4.5mm, with 29 pins. Its footprint is drawn on this page.

Where is the L6472H datasheet?

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

Where can I order the L6472H?

JLCPCB lists it as part C222397, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L6472H?

Parts like it in the library: the L6472HTR by STMicroelectronics, the DRV8814PWPR by Texas Instruments and the DRV8841PWP by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
