Questions

Is there a KiCad symbol and footprint for the HT8089ARTZ?

Yes. The symbol is EasyEDA_Cloud:AX3701ABA and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT8089ARTZ?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the HT8089ARTZ datasheet?

HTCSEMI publishes it: the Datasheet link on this page opens it.

Where can I order the HT8089ARTZ?

JLCPCB lists it as part C5158913, with 3,078 in stock; the sellers' links on this page open their listings.

What can replace the HT8089ARTZ?

Parts like it in the library: the ETA3409S2F by etasolution, the RY3430 by RYCHIP Semiconductor Inc., the TMI3113B by TMI and the ETA3448S2F by etasolution. Check their datasheets: a part that fits the footprint may still differ in its ratings.
