threshold temperature, this charge control block can reduce
the charge current to prevent further die temperature rise.
LOGIC
Logic Control and Status Indication
charger and indicates the charger status. It takes the signals
from the input voltage monitor, VIN-BAT comparator, EOC,
and the external enable signal, and determines the on and off
states as well as the charge status indication outputs of the
charger (CHG and PPR).
