MCP73841T-420I/UN

The MCP73841 device is highly advanced linear charge management controllers for use in space-limited, cost-sensitive applications. The MCP73841 combines 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 provides complete, fully-functional, stand-alone charge management solutions. The MCP73841 is designed for applications utilizing single-cell Lithium-Ion or LithiumPolymer battery packs. Two preset voltage regulation options are available (4.1V and 4.2V) for use with either coke or graphite anodes. The MCP73841 operates with an input voltage range of 4.5V to 12V. The MCP73841 device is fully specified over the ambient temperature range of -40°C to +85°C.
