The MCP73861 is a highly advanced linear charge management controller for use in space limited, high-performance applications. The MCP73861 integrates most of the external components (pass transistor, reverse blocking protection, current sensing) and combines high-accuracy constant voltage, constant current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, and charge status and fault indication in a space-saving 16-pin, 4 x 4 QFN package. The MCP73861 provides a complete, fully-functional, stand-alone charge management solution for single-cell Li-Ion and Li-Polymer applications.
