Questions
Is there a KiCad symbol and footprint for the TD9521B?
Yes. The symbol is EasyEDA_Cloud:TD9521A 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 TD9521B?
SOT-23-5, with 5 pins. Its footprint is drawn on this page.
Where is the TD9521B datasheet?
Techcode Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the TD9521B?
JLCPCB lists it as part C2935203, with 3,004 in stock; the sellers' links on this page open their listings.
What can replace the TD9521B?
Parts like it in the library: the SY6280AAC by 矽力杰silergy, the AP2171WG by Diodes Incorporated, the TPS2051BDBV by Texas Instruments and the RT9742CGJ5 by RICHTEK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
