Questions
Is there a KiCad symbol and footprint for the L6491D?
Yes. The symbol is Driver_FET:L6491 and the footprint Package_SO:SO-14_3.9x8.65mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L6491D?
SO-14, with 14 pins. Its footprint is drawn on this page.
Where is the L6491D datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L6491D?
JLCPCB lists it as part C2970144, with 694 in stock; the sellers' links on this page open their listings.
What can replace the L6491D?
Parts like it in the library: the IRS21864STR(UMW) by UMW, the UCC27714DR(UMW) by UMW, the IR21094STRPBF by Infineon Technologies and the EG21814 by EG Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
