CN3306 Datasheet | CONSONANCE

Description : The CN3306 is PWM mode step-up multi-chemistry battery charger IC. Its input voltage range is from 4.5V to 32V, also can be powered by photovoltaic cell with MPPT function. The CN3306 is ideal for lithium ion battery, Li Fe PO4 battery and Titanate Battery’s charge management with few external ponents. CN3306 adopts constant current(CC) and constant voltage(CV) mode. In constant current mode, charge current is set by an external resistor; In constant voltage mode, the regulation voltage is set by external resistors. In constant charge mode, when charge current falls below 16.6% of constant current, the charge is terminated. In charge termination mode, when battery voltage falls below 95.8% of the regulation voltage in CV mode, a new charge cycle is started again. Other functions include chip shutdown, battery overvoltage protection, built-in 5V voltage...
