Is there a KiCad symbol and footprint for the TS472IQT?
Yes. The symbol is EasyEDA_Cloud:TS472IQT and the footprint EasyEDA_Cloud:VQFN-24_L4.0-W4.0-P0.50-BL-EP2.3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TS472IQT?
QFN-24(4x4), with 25 pins. Its footprint is drawn on this page.
Where is the TS472IQT datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TS472IQT?
JLCPCB lists it as part C155583, with 3,913 in stock; the sellers' links on this page open their listings.
What can replace the TS472IQT?
Parts like it in the library: the WM8940GEFL/RV by Cirrus Logic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
