Description

The MCP73213 is a highly integrated Li-Ion battery

charge management controller for use in space-limited

and

cost-sensitive

applications.

The

MCP73213

provides specific charge algorithms for dual-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 MCP73213 ideally suitable for

portable applications. The absolute maximum voltage,

up to 18V, allows the use of MCP73213 in harsh

environments, such as low cost wall wart or voltage

spikes from plug/unplug.

The MCP73213 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 MCP73213 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 MCP73213 also serves as enable

pin. When high impedance is applied, the MCP73213

will be in standby mode.

The MCP73213 is fully specified over the ambient

temperature range of -40°C to +85°C. The MCP73213

is available in a 10 lead, DFN package.
