4.2V dual output li-ion battery charger

DBL042060_2       Specification of Battery Charger    
 
1： Brief：
DBL042060_2,  4.2V/0.6A*2. Duel outputs, for 2 single cells 3.6V Li-ion battery. When a battery is connect to the charger output. If the BATTERY is less than 2.8V, the charger enters trickle charge mode. In this mode, the charger supplies approximately 1/10 the Rated charge current to bring the battery voltage up. When the BAT voltage rises above 2.8V, the charger enters constant-current mode, where the Rated charge current is supplied to the battery. When the BAT voltage approaches the final float voltage (4.2V), the charger enters constant-voltage mode and the charge current begins to decrease. When the charge current drops to 1/10 of the Rated value, the charge cycle ends.
2： Special Feature:
