Dear team,
My customer are using bq40z80, and they found the communication sometimes failed when startup and they think the power sequence will influence the communication. I wonder if their schematic is OK. So could you kindly review the schematic and give some suggestion? They used 2 bq40z80 for 6S2P battery.
Thanks.
Best regards,
