Description
The MCP73871 device is a fully integrated linearsolution for system load sharing and Li-Ion / Li-Polymerbattery charge management with ac-dc wall adapter
and USB port power sources selection. It’s alsocapable of autonomous power source selection
between input or battery. Along with its small physicalsize, the low number of required external components makes the device ideally suited for portable
applications.
The MCP73871 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).
The MCP73871 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 supports up to 1.8A total current for system load and battery charge current.
