Applications
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.
