Microchip MCP73871-2CCI/ML MCP73871-2CCI/ML Battery Charger for 1 Cell of Li-Ion Li-Pol 6V Input 4.2V / 1A Charge QFN-20

The MCP73871-2CCI/ML is a stand-alone system load sharing and Li-ion/Li-polymer battery charge Management Controller with AC-DC wall adapter and USB port power sources selection. It is also capable of autonomous power source selection between input or battery. This device automatically obtains power for the system load from a single-cell Li-Ion battery or an input power source (AC-DC wall adapter or USB port). This device specifically adheres to the current drawn limits governed by the USB specification. With an AC-DC wall adapter providing power to the system, an external resistor sets the magnitude of 1A maximum charge current while supporting up to 1.8A total current for system load and battery charge current. This device employs a constant current/constant voltage (CC/CV) charge algorithm with selectable charge termination point.
