        Advanced Single or Dual Cell Lithium-Ion/

  Lithium-Polymer Charge Management Controllers

Features                                            Description

� Linear Charge Management Controllers              The MCP7384X family of devices are highly advanced

� High-Accuracy Preset Voltage Regulation:          linear charge management controllers for use in

                                                   space-limited, cost-sensitive applications. The

  - + 0.5% (max)                                   MCP73841 and MCP73842 combine high accuracy,

� Four Preset Voltage Regulation Options:           constant-voltage, constant-current regulation, cell pre-

                                                   conditioning, cell temperature monitoring, advanced

  - 4.1V - MCP73841-4.1, MCP73843-4.1              safety timers, automatic charge termination and

  - 4.2V - MCP73841-4.2, MCP73843-4.2              charge status indication in space-saving, 10-pin

  - 8.2V - MCP73842-8.2, MCP73844-8.2              MSOP packages. The MCP73841 and MCP73842

  - 8.4V - MCP73842-8.4, MCP73844-8.4              provide complete, fully-functional, stand-alone charge

� Programmable Charge Current                       management solutions.

� Programmable Safety Charge Timers

� Preconditioning of Deeply Depleted Cells          The MCP73843 and MCP73844 employ all the

� Automatic End-of-Charge Control                   features of the MCP73841 and MCP73842, with the

� Optional Continuous Cell Temperature              exception of the cell temperature monitor. The
