Lithium Ion Battery Charger for Solar-Powered Systems
CN3083
General Description:
The CN3083 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 8-bit ADC can adjust charging current automatically based on the output capability of input power supply, so CN3083 is ideally suited for solar powered system. Furthermore, the CN3083 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.
