ral Descriptions: The CN3791 is a PWM switch-mode lithium ion battery charger controller that can be powered by photovoltaic cell with maximum power point tracking function with few external components. The CN3791 is specially designed for charging lithium ion batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage can be fixed at 4.2V with ± 1% accuracy. The constant charge current is programmable with a single current sense resistor. Deeply discharged batteries are automatically trickle charged at 17.5% of the full-scale current until the cell voltage exceeds 66.5% of c
