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.
The MCP73861/3 is intended for applications utilizing single-cell Lithium-Ion or Lithium-Polymer battery packs, while the MCP73862/4 is intended for dual series cell Lithium-Ion or Lithium-Polymer battery packs.
The MCP73861/3 has two selectable voltage-regulation options available (4.
1V and 4.
2V), for use with either coke or graphite anodes and operate ...
