MCP73862

The MCP7386X family of devices are highly advanced linear charge management controllers for use in spacelimited, cost-sensitive applications. The MCP73861 and MCP73862 combine high-accuracy constant voltage, constant current regulation, cell preconditioning, cell temperature monitoring, advanced safety timers, automatic charge termination, internal current sensing, reverse-blocking protection, and charge status and fault indication in a space-saving 16-pin, 4 x 4 QFN package.

The MCP7386X provides a complete, fully-functional, stand-alone charge management solution with a minimum number of external components.

The MCP73861 is targeted for applicatioins utilizing single-cell Lithium-Ion or Lithium-Polymer battery packs, while the MCP73862 is targeted for dual series cell Lithium-Ion or Lithium-Polymer battery packs. The MCP73861 has two selectable voltage-regulation options available (4.1V and 4.2V), for use with either coke or graphite anodes, and operates with an input voltage range of 4.5V to 12V. The MCP73862 has two selectable voltage-regulation options available (8.2V and 8.4V), for use with coke or graphite anodes, and operates with an input voltage range of 8.7V to 12V.

The MCP7386X family of devices are fully specified over the ambient temperature range of -40 to +85.
