Is there a KiCad symbol and footprint for the BL8812B?
Yes. The symbol is EasyEDA_Cloud:BL8812B and the footprint EasyEDA_Cloud:SOP-8_7P-L4.9-W3.9-P1.27-LS6.0-BL-PE7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BL8812B?
SOP-7, with 7 pins. Its footprint is drawn on this page.
Where is the BL8812B datasheet?
BL publishes it: the Datasheet link on this page opens it.
Where can I order the BL8812B?
JLCPCB lists it as part C7435970, with 1,799 in stock; the sellers' links on this page open their listings.
What can replace the BL8812B?
Parts like it in the library: the OB25133JPA by OB, the PN8370SSC-R1H by Wuxi Chipown Micro-electronics, the PN8366SSC-R1M by Wuxi Chipown Micro-electronics and the KP2143SGA by Kiwi Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
