Questions
Is there a KiCad symbol and footprint for the BQ4285EP?
Yes. the footprint Package_DIP:DIP-24_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BQ4285EP?
PDIP-24, with 5 pins. Its footprint is drawn on this page.
Where is the BQ4285EP datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the BQ4285EP?
JLCPCB lists it as part C3304043, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BQ4285EP?
Parts like it in the library: the DS12CR887-33+ by Maxim Integrated (Analog Devices), the DS12885N+ by Maxim Integrated (Analog Devices), the DS12885+ by Maxim Integrated (Analog Devices) and the DS17485-3+ by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
