Description:

CN3065 500mA
This is a supper 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 500mA with a maximum recommended input of 6V (minimum 4.4V). It's recommended that batteries not be charged at greater than their capacity rating.

CN3065 900mA
The CN3065 is a single-cell lithium battery charge management chip that can be powered by solar panels. The device includes a power transistor internally that does not require an external current sense resistor and blocking diode. The internal 8-bit analog-to-digital conversion circuit automatically adjusts the charging current according to the current output capability of the input voltage source. The user does not need to consider the worst case, and can maximize the current output capability of the input voltage source, which is very suitable for using solar panels. Lithium battery charging applications powered by voltage sources with limited current output capability. The CN3065 requires very few peripheral components and is compliant with USB bus specifications, making it ideal for portable applications. The thermal modulation circuit can control the temperature of the chip within a safe range when the power consumption of the device is relatively large or the ambient temperature is relatively high. The internal fixed constant voltage charging voltage is 4.2V and can also be adjusted by an external resistor. The charging current is set by an external resistor. When the input voltage is powered down, the CN3065 automatically enters a low-power sleep mode where the battery draws less than 3 microamps. Other features include low input latching, automatic recharge, battery temperature monitoring, and charge status/charge end status indication.

Charge a single rechargeable lithium battery with a USB port or AC adapter

Input voltage range: 4.4V to 6V

On-chip power transistor, no external blocking diode and current sense resistor required

Constant voltage charging voltage 4.2V, can also be adjusted by an external resistor

In order to activate deep discharge batteries and reduce power consumption, use a small current precharge mode when the battery voltage is low?

User-settable constant current charging current up to 900MA

Charging in constant current / constant voltage / constant temperature mode can maximize the charging current and prevent the chip from overheating

Automatically enters a low-power sleep mode when the power supply voltage is powered down. • Dual indication output for charge status and charge end status

C/10 end of charge detection

Automatic recharge

Charging status and charging end status dual indication output: red light charging status; green light charging end state; red light flashing, green light is always on, the battery is not connected.
