Other Parts Discussed in Thread: BQ76940, BQ78350

Hello,

We get a customer who wants to use BQ76940+BQ78350 to accomplish 15 cells monitor and protection.

Is that possible to work without MCU after configuring the setting by GUI ? Can BQ78350 monitor the voltage,current, temperature without communicating with MCU ? 

Can BQ78350 + BQ76940 do cell balance without communicating with MCU ?

Thanks a lot !

Regards

William

    Yes, be sure to connect /PRES and /KEYIN pins appropriately to keep the pack on.  Adjust the sleep setting if needed.  If the gauge will not be used or set up properly, it may be best to disable the overcharge protection.
