MCP73113EV-1SOVP: Li-Ion/Li-Pol, 500mA ~ 1A @ 4.2V

Summary

The MCP73113 is a highly integrated Li-Ion battery charge management controller for use in space-limited and cost-sensitive applications. The MCP73113 provides specific charge algorithms for 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 MCP73113 ideally suitable for portable applications.

The absolute maximum voltage, up to 18V, allows the use of MCP73113 in harsh environments, such as low cost wall wart.

The MCP73113 employs a constant current / constant voltage charge algorithm. The various charging voltage regulations provide design engineers flexibility to use in different applications. The fast charge, constant current value is set with one external resistor from 130 mA to 1100 mA. The MCP73113 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 PROG pin of the MCP73113 also serves as enable pin. When high impedance is applied, the MCP73113 will be in standby mode.
