Questions

Is there a KiCad symbol and footprint for the TM1640B?

Yes. The symbol is EasyEDA_Cloud:MSTM1640(SOP28) and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1640B?

SOP-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the TM1640B datasheet?

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

Where can I order the TM1640B?

JLCPCB lists it as part C2962200, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TM1640B?

Parts like it in the library: the HTM1628 by HXY MOSFET, the ISL97687IBZ by Renesas Electronics, the BD9420F-GE2 by ROHM Semiconductor and the HTM1640 by HXY MOSFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
