CN3703 5A 3 Cell Standalone Li-ion Battery Charger IC SMD TSSOP16

General Descriptions:The CN3703 is a PWM switch-mode lithium ion battery charger controller for 3 cell li-ion battery in a small package using few external components. The CN3703 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 12.6V with ±1% accuracy.The constant charging current is programmable with a single sense resistor. Deeply discharged batteries are automatically trickle charged at15% of the programmed constant charging current until the cell voltage exceeds 8.4V.The charge cycle is terminated once the charging current drops to a level set by an on-chip resistor and an external resistor, and a new charge cycle automatically restarts if the battery voltage falls below 12V. CN3703 will automatically enter sleep mode when input voltage is lower than battery voltage.Other features include undervoltage lockout, battery temperature monitoring and status indication, etc.CN3703 is availablein a space-saving 16-pin TSSOP package.
