The cxlb7210 is a PWM mode lithium battery or lithium iron phosphate battery charging management integrated circuit, which can independently manage the charging of single or multiple lithium batteries or lithium iron phosphate batteries. It has the advantages of small package, less peripheral components and simple use. Cxlb7210 has constant current and voltage charging mode, which is very suitable for lithium battery or lithium iron phosphate battery. Cxlb7210 has constant current and voltage charging mode, which is very suitable for lithium battery or lithium iron phosphate battery or lithium iron phosphate battery. In the constant voltage charging mode, the constant voltage charging voltage is set by the external resistance partial voltage network; in the constant current charging mode, the charging current is set by an external resistance. For deeply discharged batteries, when the battery voltage is lower than 66.7% of the set constant voltage charging voltage, the cxlb7210 uses 15% of the set constant current charging current to charge the battery
Trickle charging. In the constant voltage charging stage, the charging current decreases gradually. When the charging current decreases to the value set by the external resistance, the charging ends. At the end of charging state, if the battery voltage drops to 91.1% of the set constant voltage charging voltage, a new charging cycle will start automatically
