BQ76925: What to do with unused pins?

Part Number: BQ76925

I will not be using the current or temperature monitoring features of the bq76925. I would still like to use the ALERT pin for wakeup functionality. Can I simply tie the SENSEN and SENSEP pins together? Can the VTB and VIOUT pins be left floating? Do any of these pins need to be tied to VSS through a capacitor? Thanks!

    Hi Seth,
    If SENSEN and SENSEP are not used they can be tied together. They are inputs and should be tied to VSS.
    VTB and VIOUT are outputs and can be left floating if they are not used. No capacitor is needed if the outputs are not turned on.
