Description:
The MCP73113/4 are highly integrated Li-Ion battery
charge management controllers for use in
space-limited and cost-sensitive applications. The
MCP73113/4 devices provide specific charge
algorithms for Li-Ion/Li-Polymer batteries to achieve
optimal capacity and safety in the shortest charging
time possible. Along with their small physical size, the
low number of external components make the
MCP73113/4 ideally suitable for portable applications.
The absolute maximum voltage, up to 18V, allows the
use of MCP73113/4 in harsh environments, such as
low cost wall wart or voltage spikes from plug/unplug.
The MCP73113/4 devices employ 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 MCP73113/4
devices limit 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 MCP73113/4 also serves as
enable pin. When high-impedance is applied, the
MCP73113/4 will be in Standby mode.
The MCP73113/4 devices are fully specified over the
ambient temperature range of -40°C to +85°C. They
are available in a 10-lead, DFN package.
