Hi team,

Could you help to review the sch of BQ27Z746? I have checked the other design but not sure that BAT_SP, BAT_SN could be floated or not. Thanks!

    Hello Kailun, 

    BAT_SP and BAT_SN can be left floating. I do not see any obvious errors with the schematic here. Something to note is that since you have ENAB pulled down, the gauge will not be able to enter shutdown mode with this configuration. So if you are planning to use shutdown mode then you should not pull ENAB down to ground. 

    Regards, 

    Jonny.
