CN3795 4A Multi-Chemistry Battery Charger IC With Photovoltaic Cell MPPT Function - SSOP-10

Datasheet

CN3795 is a PWM step-down converter that can be powered by solar panels. Voltage mode multi-cell battery charge management integrated circuit, independently charging multiple cells Battery charging is managed, with a small package size and peripheral components It has the advantages of less parts and simple use.

The CN3795 is specially designed for charging lithium ion，LiFePO4 or Lithium Titanate batteries with constant current and constant voltage mode. In constant voltage mode, there gulation 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.The charge cycle is terminated once the charging current drops to 16% of full-scale current, and a new charge cycle automatically restarts if the charge current rises above 58.8% of full-scale charge current. CN3795 will automatically enter sleep mode when input voltage is lower than battery voltage.
