OPERATION
(1) As shown in the above chart, charging starts with maximum current IL (given by the formula 0.7
IRL) and the battery voltage increases gradually.
(2) When the battery voltage reaches VCU (Charging Voltage), the voltage is fixed at VCU, that is
the constant voltage charging state. And the charging current decreases gradually.
(3) When the charging current decreases to the point of ICU, the voltage starts dropping. The
voltage dropping continues until the current reaches 'CL: and is settled at the Focusing Voltage
NCL). And the voltage dropping ratio is given by the formula (VcU-VcL)/(lcu -1/CL) and it's
center is VCS and Ics.
(4) The center of the voltage dropping curve is ICS, which is given by the formula 0.2 (RC : External
Resistor).
(5) LED indicates as a charging monitor during the charging current is greater than ICL. When it
becomes lower than Ity, LED turns off for the indication of charging completion. Internal
resistance is 1kQ and external resistor is needed at Vcc215V.
