1.Description:
  It is a lithium battery solar charging board.
  It uses CN3065 chip, a single-cell lithium battery charging management chip used for solar panel power supply.
  The device includes a power transistor inside, and does not require external current detection resistors and blocking diodes in application.
  The internal 8-bit analog-digital conversion circuit can automatically adjust the charging current according to the current output capability of the input voltage source.

2.Feature:
  1).It can make maximum use of the current output capability of the input voltage source.
Very suitable for lithium battery charging applications powered by voltage sources with limited current output capabilities such as solar panels.

  2).CN3065 requires very few peripheral components and complies with USB bus technical specifications.
Very suitable for the field of portable applications.

  3).It can use a variety of input power sources to charge the lithium battery.
These input power sources can be the voltage output by the USB interface, the wall adapter, or the solar panel.

  4).The charging current is set by an external resistor.
When the input voltage is powered off, CN3065 automatically enters a low-power sleep mode.
The current consumption of the battery is less than 3uA.

3.Parameter:
  1).Product Name:Lithium Battery Solar Charging Board
  2).Input Voltage:DC 4.4V-6V
  3).Maximum Charging Current:500mA
  4).Work Temperature:-40℃~85℃
  5).Work Humidity:5%~95%RH
  6).Size:45*20*9mm

4.Battery Charging Instructions:
  When charging the battery, take priority from the external power supply; but when the load current consumption is greater than the charging current, it will also take power from the battery. If the input is not enough, the battery will slowly run out. If the load consumption is small, the battery will be fully charged slowly.

5.Package:
  1pcs Lithium Battery Solar Charging Board
