The MCP73841 and MCP73842 combine high accuracy, constant-voltage, constant-current regulation, cell pre- conditioning, cell temperature monitoring, advanced safety timers, automatic charge termination and charge status indication in space-saving, 10-pin MSOP packages. The MCP73841 and MCP73842 provide complete, fully-functional, stand-alone charge management solutions. The MCP73843 and MCP73844 employ all the features of the MCP73841 and MCP73842, with the exception of the cell temperature monitor. The MCP73843 and MCP73844 are offered in 8-pin MSOP packages. The MCP73841 and MCP73843 are designed for applications utilizing single-cell Lithium-Ion or Lithium- Polymer battery packs. Two preset voltage regulation options are available (4.1V and 4.2V) for use with either coke or graphite anodes. The MCP73841 and MCP73843 operate with an input voltage range of 4.5V to 12V. The MCP73842 and MCP73844 are designed for applications utilizing dual series cell Lithium-Ion or Lithium-Polymer battery packs. Two preset voltage regulation options are available (8.2V and 8.4V). The MCP73842 and MCP73844 operate with an input voltage range of 8.7V to 12V. The MCP7384X family of devices are fully specified over the ambient temperature range of -40°C to +85°C.
