Adafruit Universal USB / DC / Solar Lithium Ion/Polymer Charger

DESCRIPTION This charger is the only one you need to keep all your Lithium Polymer (Li - Poly) or Lithium Ion (Li - Ion) rechargeable batteries topped up. No matter the power source at your disposal! The Adafruit Universal USB / DC / Solar Lithium Ion/Polymer Charger can use USB, DC or Solar power, with a wide 5-10V input voltage range! The charger chip is super smart, and will reduce the current draw if the input voltage starts to dip under 4.5V, making it a perfect near-MPPT solar charger that you can use with a wide range of panels. Compared to our earlier, MCP73871-based charger this universal charger has some nice improvements: USB Type C port for modern computers and chargers Up to 1.5A charge rate Up to 10V input voltage, 28V protected Load output is regulated to never be over 4.4V so its safe for 3.3V regulators or 5V boost converters No stabilization capacitor needed (although you can add one if you like!) Same load sharing so that DC/USB/Solar is prioritized over battery powe
