Lithium-Ion, Polymer Lipo Battery Charger IC, USB, SOT23 – MAX1555
This handy little IC will correctly and safely charge our Lithium Polymer batteries with power from a USB port or from a DC wall adapter.
Max current is limited to 300mA using an external wall supply (3.7V to 7V). Requires almost no external components and will automatically select between a DC source and USB source if both are present. Current is automatically reduced to a trickle when charging is complete.
- Charge from USB or AC Adapter
- Automatic Switchover when AC Adapter is Plugged In
