Is there a KiCad symbol and footprint for the M41ST85WMX6?
Yes. The symbol is EasyEDA_Cloud:M41ST85WMX6TR and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the M41ST85WMX6?
SOIC-28-300mil, with 28 pins. Its footprint is drawn on this page.
Where is the M41ST85WMX6 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the M41ST85WMX6?
JLCPCB lists it as part C2651507, with 2 in stock; the sellers' links on this page open their listings.
What can replace the M41ST85WMX6?
Parts like it in the library: the BQ4802LYDW by Texas Instruments, the DS1501WZ+ by Analog Devices, the V3025SO28A+ by EM Microelectronic and the V3025SO28B+ by EM Microelectronic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
