• Low-Cost 2-Cell Li-Ion/Li-Poly Chargers/CradlesThe MCP73213 is a highly integrated Li-Ion batterycharge management controller for use in space-limitedand cost-sensitive applications. The MCP73213provides specific charge algorithms for dual-cell Li-Ion/Li-Polymer batteries to achieve optimal capacity andsafety in the shortest charging time possible. Alongwith its small physical size, the low number of externalcomponents makes the MCP73213 ideally suitable forportable applications. The absolute maximum voltage,up to 18V, allows the use of MCP73213 in harshenvironments, such as low-cost wall wart or voltagespikes from plug/unplug.The MCP73213 employs a constant current/constantvoltage charge algorithm. The various charging voltageregulations provide design engineers flexibility to use indifferent applications. The fast charge, constant currentvalue is set with one external resistor from 130 mA to1100 mA. The MCP73213 limits the charge currentbased on die temperature during high-power or high-ambient conditions. This thermal regulation optimizesthe charge cycletime while maintaining devicereliability.The PROG pin of the MCP73213 also serves as enablepin. When high impedance is applied, the MCP73213will be in Standby mode.The MCP73213 is fully specified over the ambienttemperature range of -40°C to +85°C. The MCP73213is available in a 10-lead DFN package.
