General Descriptions:
The CN3762 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 CN3762 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 8.4V with ± 1% accuracy, also can be adjusted upwards with an external resistor. The constant charging current is programmable with a single current sense resistor.
