itch-mode lithium ion battery charger controller for 3 cell li-ion battery in a small package using few external components. The CN3703 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 12.6V 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 8.4V.
