Questions
Is there a KiCad symbol and footprint for the L5991AD?
Yes. The symbol is EasyEDA_Cloud:E-L5991AD and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L5991AD?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the L5991AD datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L5991AD?
JLCPCB lists it as part C10655, with 19 in stock; the sellers' links on this page open their listings.
What can replace the L5991AD?
Parts like it in the library: the HR1001BGS-Z by Monolithic Power Systems, the EG1165 by EG Micro, the EG1165S by EG Micro and the VIPER16LD by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
