CXLB73262 is a PWM buck mode integrated circuit for two battery charging management that can be powered by solar panels. It independently manages the charging of two batteries and has the advantages of small package size, fewer peripheral components, and simple use. CXLB73262 has trickle, constant current, and constant voltage charging modes, making it very suitable for charging management of two lithium batteries. Internal feedback resistor setting for constant voltage charging CXLB73262; In constant current charging mode, the charging current is set through an external resistor. When powered by solar panels, the internal circuit can automatically track the maximum power point of the solar panel, and users do not need to consider the worst-case scenarioMaximizing the output power of solar panels is highly suitable for applications powered by solar panels. For deep discharge lithium batteries, when the battery voltage is lower than 66.6% (typical value) of the constant voltage charging voltage, CXLB73262 uses 25% of the set constant current charging current to perform trickle charging on the battery. During the constant voltage charging phase, the charging current gradually decreases. When the charging current drops to 15% of the constant current charging current, the charging process ends. At the end of charging, if the battery voltage drops below 95.8% of the constant voltage charging voltage, a new charging cycle will automatically begin. When the input power fails or the input voltage is lower than the battery voltage, CXLB73262 automatically enters sleep mode. Other features include JEITA compliant battery temperature monitoring, input low voltage latch, battery terminal overvoltage protection, and status indication. CXLB73262 adopts a heat dissipation enhanced 10 pin SSOPEncapsulation (eSSOP-10).
