        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

  Monitoring (MCP73841 and MCP73842)               MCP73843 and MCP73844 are offered in 8-pin MSOP

� Charge Status Output for Direct LED Drive         packages.

� Automatic Power-Down when Input Power

  Removed                                          The MCP73841 and MCP73843 are designed for

� Temperature Range: -40�C to 85�C                  applications utilizing single-cell Lithium-Ion or Lithium-

� Packaging: MSOP-10 - MCP73841, MCP73842           Polymer battery packs. Two preset voltage regulation

                                                   options are available (4.1V and 4.2V) for use with either

                  MSOP-8 - MCP73843, MCP73844      coke or graphite anodes. The MCP73841 and

                                                   MCP73843 operate with an input voltage range of 4.5V

Applications                                        to 12V.

� Lithium-Ion/Lithium-Polymer Battery Chargers      The MCP73842 and MCP73844 are designed for

� Personal Data Assistants                          applications utilizing dual series cell Lithium-Ion or

� Cellular Telephones                               Lithium-Polymer battery packs. Two preset voltage

� Hand-Held Instruments                             regulation options are available (8.2V and 8.4V). The

� Cradle Chargers                                   MCP73842 and MCP73844 operate with an input

� Digital Cameras                                   voltage range of 8.7V to 12V.

� MP3 Players

                                                   The MCP7384X family of devices are fully specified

                                                   over the ambient temperature range of -40�C to +85�C.
