MCP73838 Overview
The MCP73837 and MCP73838 devices are fully integrated linear Li-Ion / Li-Polymer battery chargers with autonomous power source selection. Along with its small physical size, the low number of external ponents required makes the MCP73837/8 ideally suitable for portable applications. The MCP73837/8 automatically selects the USB-Port or AC-Adapter as the power source for the system.
