Description:

The MCP7386X family of devices features highly advanced linear charge management controllers for use in space-limited, cost-sensitive applications. The devices combine high-accuracy, constant voltage and current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, internal current sensing, reverse-blocking protection, charge status and fault indication in either a space-saving 16-pin 4 x 4 QFN package, or a 16-pin SOIC package. The MCP7386X provides a complete, fully functional, stand-alone charge management solution with a minimum number of external components.
