CN3704 Datasheet | CONSONANCE

CONSONANCE 5A, Standalone Li-ion Battery Charger General Descriptions: The CN3704 is a PWM switch-mode lithium ion battery charger controller for 4 cell li-ion battery in a small package using few external ponents. The CN3704 is specially designed for charging lithium ion batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage is fixed at 16.8V with ±1% accuracy. The constant charging current is programmable with a single sense resistor. Deeply discharged batteries are automatically trickle charged at 15% of the programmed constant charging current until the cell voltage exceeds 11.2V. The charge cycle is terminated once the...
