Adafruit Micro-Lipo Charger

Adafruit Micro-Lipo Charger is designed for charging Lithium Polymer or Lithium-ion (LiPoly/LiIon) batteries via a USB Type-C™ connector. This charger operates by plugging into a USB port and a 3.7V/4.2V LiPoly/Li-Ion rechargeable battery into the JST plug. The Micro-Lipo charger performs charging in three stages, namely a preconditioning charge, then a constant-current fast charge, and finally, a constant-voltage trickle charge. This device features 0.1" breakout pads, D+/D- data lines, and a 100mA charge current that is adjustable to 500mA by soldering closed the jumper. The Micro-Lipo charger is RoHS2 compliant and is available in 24mm x 19mm x 7.2mm dimensions.
