CONSONANCE 5A, Standalone Li-ion Battery Charger CN3702 General Descriptions: The CN3702 is a PWM switch-mode lithium ion battery charger controller for 2 cell li-ion battery in a small package using few external components.
The CN3702 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 8.
4V 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 2.
8V/cell.
The charge cycle is terminated once the ...
