Note 1:
The qualification parameters are continuously
monitored throughout the charge cycle. For more
details on this, refer to Section 4.1 “Charge
Qualification and Preconditioning”.
Note 2:
The charge current will be scaled based on the
die temperature during thermal regulation. For
more details, refer to
Section 4.5 “Thermal
Regulation”.
