Description

The MCP73123/223 is a highly integrated Lithium Iron

Phosphate(LiFePO4) battery charge management

controller for use in space-limited and cost-sensitive

applications. The MCP73123/223 provides specific

charge algorithms for LiFePO4 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

MCP73123/223

ideally

suitable

for

various

applications. The absolute maximum voltage, up to

18V, allows the use of MCP73123/223 in harsh

environments, such as low cost wall wart or voltage

spikes from plug/unplug.

The MCP73123/223 employs a constant current /

constant voltage charge algorithm. The 3.6V per cell

factory preset reference voltage simplifies design with

2V

preconditioning

threshold.

The

fast

charge,

constant current value is set with one external resistor

from 130 mA to 1100 mA. The MCP73123/223 also

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 MCP73123/223 also serves as

enable pin. When high impedance is applied, the

MCP73123/223 will be in standby mode.

The MCP73123/223 is fully specified over the ambient

temperature range of -40°C to +85°C. The MCP73123/

223 is available in a 10 lead, DFN package.
