Operation with VBAT up to 80 V is supported when the charge pump is not in operation. Whenever the charge pump is in operation
(in 5.5 V or 11 V mode), the maximum voltage on VBAT should be reduced to ensure the voltage on CP1, CHG, and DSG does not
exceed their maximum specified voltage.
(2)
Cell voltage accuracy is specified after completion of board offset calibration
(3)
Specified by design
(4)
Voltage on VC0 can extend higher (limited by absolute maximum specification) during cell balancing.
(5)
Specified by characterization
(6)
Values may need to be optimized during system design and evaluation for best performance
