Cxlb7376 current mode fixed frequency PWM boost type multi battery charging management integrated circuit The input voltage of cxlb7376 ranges from 4.5V to 32V few peripheral components

Cxlb7376 is a current mode fixed frequency PWM boost type multi battery charging management integrated circuit. The input voltage of cxlb7376 ranges from 4.5V to 32V, with few peripheral components and simple and flexible application. It can be used for charging management of lithium battery, lithium iron phosphate battery or lithium titanate battery. The cxlb7376 has constant current and constant voltage charging mode. In the constant current charging mode, the charging current is set through an external resistance; in the constant voltage charging mode, the modulation voltage of the cxlb7376 is set by the external resistance. In the constant voltage charging stage, the charging current decreases gradually. When the charging current decreases to 16.6% of the constant current charging current, the charging ends. At the end of charging state, if the battery voltage drops to the recharging threshold, a new charging cycle will start automatically. Other functions include chip off function, battery terminal overvoltage protection function, built-in 5V voltage modulator and slope compensation.
