The MCP73113/4 are highly integrated Li-Ion battery charge management controllers for use in space-limited and cost-sensitive applications. The MCP73113/4 devices provide specific charge algorithms for Li-Ion/Li-Polymer batteries to achieve optimal capacity and safety in the shortest charging time possible. Along with their small physical size, the low number of external components make the MCP73113/4 ideally suitable for portable applications. The absolute maximum voltage, up to 18V, allows the use of MCP73113/4 in harsh environments, such as low cost wall wart or voltage spikes from plug/unplug.
