This is a super mini Solar Lipo charger based on the CN3065 – a single lithium battery charge management chip.
This Solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable LiPo battery.
Set-up is easy as well, just plug your solar panel into one side of the Solar charger and your battery into the other and you are good to start charging!
The output of the Solar Charger is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. By default, the Solar charge comes set to a maximum charge current of 1A with a maximum recommended input of 6V (minimum 4.4V).
It’s recommended that batteries not be charged at greater than their capacity rating.
The CN3065 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 CN3065 is ideally suited for solar powered system. Furthermore, the CN3065 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 is removed, the CN3065 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.
