MCP73871 USB 5V DC Power Boost Solar Lipoly Lithium Li-ion Polymer Charger Board

MCP73871 USB 5V DC Power Boost Solar Lipoly Lithium Li-ion Polymer Charger Board

MCP73871 USB 5V DC Power Boost Solar Lipoly Lithium Li-ion Polymer Charger Board. The MCP73871 device is a fully integrated linear solution for system load sharing and Li-Ion/Li-Polymer battery charge management with AC-DC wall adapter and USB port power sources selection. It is also capable of autonomous power source selection between input and battery. Along with its small physical size, the low number of required external components makes the device ideally suited for portable applications.

Make your green projects this summer with our specialized USB / Solar lithium-ion polymer battery charger. This charger is a unique design, perfect for DIY outdoor projects or iPod chargers. We have spent more than a year testing it and playing with this charger to find a plug and play solution to charge batteries with the sun and we are really satisfied with what we finished.

Easy to use. Pick up any of our many 3.7V / 4.2V LiIon batteries and a 6V solar panel. Plug the battery into the BATT port using a 2-pin JST cable and the solar panel on the DC connector using a 2.1mm adapter cable put the solar panel outside (and keep the battery out of the Sun. It needs to stay cool!) To start charging! You can feed another project as a Mintyboost at the same time by connecting to the load output port

Our carefully designed charger is designed specifically for solar charging, and will automatically attract the largest possible current from the panel in any light condition. Even thinking that it is not a “true” MPPT (Maximum Feed Point Tracker), it has almost identical performance without the additional cost of a buck converter. Other batteries may have different voltage, chemistry, polarity or pinout.

Features

• 3.7V / 4.2V lithium-ion or lithium-ion battery charger
• Charge with 5-6 V DC USB or 6 V solar panel!
• Use any 6 V solar panel
• LED indicator three colors: good power, charge 
• Low battery indicator (fixed at 3.1 V) with LED output
• Set for maximum load rate of Ma, can be adjusted from 50 mA to 1 to soldering in a resistance
• It will always draw the largest possible current from a solar cell – up to the maximum load rate!
• Intelligent load sharing automatically uses the input power when it is available, to prevent the battery from constantly charging / discharging
