The MCP73830/L devices provide specific charge algorithms for single-cell Li-Ion/Li- Polymer batteries 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 regulated constant, fast-charge current enables the design in small Li-Ion batteries and low-supply current applications. The fast-charge, constant current value is set with one external resistor from 20 mA to 200 mA. The MCP73830/L allows up to 1000 mA charge current for applications that require faster constant current. The MCP73830/L provides a thermal foldback function that limits the charge current based on die temperature during high-power or high-ambient conditions. This thermal regulation optimizes the charge cycle time while maintaining device reliability. The MCP73830/L is 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.
