Hi,
I am designing a battery charger circuit with BQ25890, here I get some questions about circuit connections, could you please me?
1. If USB function is not needed, can I leave D+, D- and DSEL pins unconnected?
2. If QON(Pin12)function unused, can I leave this pin unconnected?
3. Do I need other pins connection for this IC to MCU communication except SCL, SDA and INT pins?
