Is there a KiCad symbol and footprint for the L5972D?
Yes. The symbol is EasyEDA_Cloud:L5972D013TR and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L5972D?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the L5972D datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L5972D?
JLCPCB lists it as part C1355772, with 738 in stock; the sellers' links on this page open their listings.
What can replace the L5972D?
Parts like it in the library: the TX4143B by XDS, the AP1534SG by Diodes Incorporated, the SXL1509-5.0E1 by JSMSEMI and the AP1509-50SG by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the L5972D?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
