Microchip (MCP73213-A6SI/MF) Battery Charger for 2 Cells of Li-Ion

Battery Charger for 2 Cells of Li-Ion, Li-Pol battery, 4V input, 8.4V / 1.1A charge, DFN-10 Product Overview The MCP73213-A6SI/MF is a dual cell highly integrated Li-ion battery charge Management Controller for use in space-limited and cost-sensitive applications. The MCP73213 can accept an absolute maximum of 18V input and provides a 13V overvoltage protection. The output current can be programmable to be between 130 and 1100mA. The MCP73213 is specified over the ambient temperature range of -40 to 85°C. The MCP73213 provides specific charge algorithms for dual-cell Li-ion/Li-polymer batteries to achieve optimal capacity and safety in the shortest charging time possible. The MCP73213 employs a constant current/constant voltage charge algorithm.
