Description:

The MCP73830/L are highly integrated, Li-Ion battery

charge management controllers for use in space-

limited applications. 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.
