CXLB73260 is a PWM buck mode four cell lithium battery charging management integrated circuit that independently manages the charging of four lithium batteries. It has the advantages of small package size, fewer peripheral components, and simple use.CXLB73260 has constant current and constant voltage charging modes, which are very suitable for charging lithium batteries. In constant voltage charging mode,CXLB73260 modulates the battery voltage to 16.6V with an accuracy of ± 1%; In constant current charging mode, the charging current is passed throughSet an external resistor. For deep discharge lithium batteries, when the battery voltage is below 11.2V, CXLB73260 uses 15% of the set constant current charging current to trickle charge the battery. During the constant voltage charging phase, the charging current gradually decreases. When the charging current drops to the value set by the external resistor, the charging process ends. At the end of charging, if the battery voltage drops to 16V, a new charging cycle will automatically begin. When the input power fails or the input voltage is lower than the battery voltage, CXLB73260 automatically enters sleep mode. Other functions include input low voltage latch, battery temperature monitoring, battery terminal overvoltage protection, and charging status indication. CXLB73260 adopts a 16 pin TSSOP package.
