The MCP73844 device is highly advanced linear charge management controllers for use in space-limited, cost-sensitive applications. The MCP73844 combine high accuracy, constant-voltage, constant-current regulation, cell preconditioning, advanced safety timers, automatic charge termination and charge status indication in space-saving, 8-pin MSOP packages. The MCP73844 provides complete, fully-functional, stand-alone charge management solutions. The 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 MCP73844 operate with an input voltage range of 8.7V to 12V. The MCP73844 device is fully specified over the ambient temperature range of -40°C to +85°C.
