CONSONANCE 4A, Multi-Chemistry Battery Charger CN3765 General Descriptions: The CN3765 is a PWM switch-mode multi-chemistry battery charger controller in a small package using few external components. The CN3765 is specially designed for charging lithium ion，LiFePO4 or Lithium Titanate batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage is set by 2 external resistors. The constant charging current is programmable with a single current sense resistor. Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed constant charging current until the cell voltage exceeds 66.5% of constant voltage.
