The MCP73830/L devices provide specific charge algorithms for single-cell Li-Ion/Li-Polymer batter- ies to achieve optimal capacity and safety in the shortest charging time possible. Along with its small physical size, the low number of external components makes the MCP73830/L ideally suitable for portable applications. The MCP73830L employs a constant-current/constant voltage charge algorithm. The minimum 20 mA regu- lated constant, fast charge current enables the design in small Li-Ion batteries and low supply current applica- tions. The fast charge, constant-current value is set with one external resistor, from 20 mA to 200 mA. The MCP73830 allows up to 1000 mA charge current for applications that require faster constant current. The MCP73830/L devices provide a thermal foldback function that limits the charge current, based on die temperature during high-power or high-ambient condi- tions. This thermal regulation optimizes the charge cycle time while maintaining device reliability. The MCP73830/L devices are fully specified over the ambient temperature range of -40°C to +85°C. The MCP73830/L is available in a 6 lead, TDFN package. Package Types (Top View) MCP73830/L 2x2 TDFN * * Includes Exposed Thermal Pad (EP); see Table 3-1.
