Questions
Is there a KiCad symbol and footprint for the HT7991?
Yes. The symbol is EasyEDA_Cloud:HT7991 and the footprint Package_TO_SOT_SMD:SOT-23-6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7991?
SOT-23-6, with 6 pins. Its footprint is drawn on this page.
Where can I order the HT7991?
JLCPCB lists it as part C259960, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HT7991?
Parts like it in the library: the TPS562201DDC by Texas Instruments, the TPS561201DDCR by Texas Instruments, the SX1308 by SX and the ETA8120S2G by etasolution. Check their datasheets: a part that fits the footprint may still differ in its ratings.
