Questions

Is there a KiCad symbol and footprint for the BL6523B?

Yes. The symbol is EasyEDA_Cloud:BL6523B and the footprint Package_SO:SSOP-24_5.3x8.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL6523B?

SSOP-24, with 24 pins. Its footprint is drawn on this page.

Where is the BL6523B datasheet?

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

Where can I order the BL6523B?

JLCPCB lists it as part C918185, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BL6523B?

Parts like it in the library: the ADE7755ARS by Analog Devices, the HT7755ARSZ by HTCSEMI, the MCP3909-I/SS by Microchip Technology and the AD7755ARS by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
