MCP73841/MCP73842/MCP73843/MCP

The MCP7384X family of devices are highly advanced
linear charge management controllers for use in
space-limited, cost-sensitive applications. The
MCP73841 and MCP73842 combine high accuracy,
constant-voltage, constant-current regulation, cell preconditioning,
cell temperature monitoring, advanced
safety timers, automatic charge termination and
charge status indication in space-saving, 10-pin
MSOP packages. The MCP73841 and MCP73842
provide complete, fully-functional, stand-alone charge
management solutions.
The MCP73843 and MCP73844 employ all the
features of the MCP73841 and MCP73842, with the
exception of the cell temperature monitor. The
MCP73843 and MCP73844 are offered in 8-pin MSOP
packages.
The MCP73841 and MCP73843 are designed for
applications utilizing single-cell Lithium-Ion or Lithium-
Polymer battery packs. Two preset voltage regulation
options are available (4.1V and 4.2V) for use with either
coke or graphite anodes. The MCP73841 and
MCP73843 operate with an input voltage range of 4.5V
to 12V.
The MCP73842 and MCP73844 are designed for
applications utilizing dual series cell Lithium-Ion or
Lithium-Polymer battery packs. Two preset voltage
regulation options are available (8.2V and 8.4V). The
MCP73842 and MCP73844 operate with an input
voltage range of 8.7V to 12V.
The MCP7384X family of devices are fully specified
over the ambient temperature range of -40°C to +85°C.
