The regulation voltage is factory set to 4.2V, 4.35V,
4.40V, or 4.50V with a tolerance of ±0.75%.
4.6
The charge cycle is terminated when, during Constant-
Voltage mode, the average charge current diminishes
below a percentage of the programmed charge current
(established with the value of the resistor connected to
the PROG pin). A 1 ms filter time on the termination
comparator ensures that transient load conditions do
not result in premature charge cycle termination. The
percentage or ratio of the current is factory set. Refer to
Section 1.0 “Electrical Characteristics” for charge
termination

charge cycle begins and current is once again supplied
to the battery or load. The recharge threshold is factory
