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