Lipo Battery Charger IC, USB, SOT23 - MAX1555

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.

MAX1555 Features:

• Charge from USB or AC Adapter
• Automatic Switchover when AC Adapter is Plugged In
• On-Chip Thermal Limiting Simplifies Board Design
• Charge Status Indicator
• 5-Pin Thin SOT23 Package
