Hi Teams,

How to understand COMHP/COMHN/COMLP/COMLN to CVSS can go to +/-20V? But the other daisy chain specs are only 5.5V or 6V.

Hi Marsh,

The +/- 20V on the COM pins comes from external sources such as EV inverter noise. For more information about this voltage, we have an applications note: BQ79616-Q1 Daisy Chain Communications

Best regards,
