Questions

Is there a KiCad symbol and footprint for the TM1929?

Yes. The symbol is EasyEDA_Cloud:TM1929 and the footprint Package_SO:QSOP-24_3.9x8.7mm_P0.635mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1929?

QSOP-24-150mil, with 24 pins. Its footprint is drawn on this page.

Where is the TM1929 datasheet?

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

Where can I order the TM1929?

JLCPCB lists it as part C5174517, with 482 in stock; the sellers' links on this page open their listings.

What can replace the TM1929?

Parts like it in the library: the STP16CPC26P by STMicroelectronics, the LED1642GWP by STMicroelectronics, the MAX6964AEG+T by Maxim Integrated (Analog Devices) and the TM1646-QSOP24 by TM. Check their datasheets: a part that fits the footprint may still differ in its ratings.
