Lithium Ion Battery Charger for Solar-Powered Systems
Product Profile
    Reference Note
General Description£º
The CN3163 is a complete constant-current /constant voltage linear charger for single cell Li-ion and Li Polymer
rechargeable batteries. The device contains an on-chip power MOSFET and eliminates the need for the external
sense resistor and blocking diode.An on-chip adaptive cell can adjust charging current automatically based on the
output capability of input power supply, so CN3163 is ideally suited for solar powered system. Furthermore,the
CN3163 is specifically designed to work within USB power specifications. Thermal feedback regulates the charge
current to limit the die temperature during high power operation or high ambient temperature.
The regulation voltage is internally fixed at 4.2V with 1% accuracy, it can also be adjusted with an external
resistor. The charge current can be programmed externally with a single resistor. When the input supply s removed,
i the CN3163 automatically enters a low power sleep mode , dropping the battery drain current to less than 3uA.
Other features include undervoltage lockout, automatic recharge, battery temperature sensing and
charging/termination indicator.
The CN3163 is available in a thermally enhanced 8-pin SOP package.
