INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP73831 Evaluation Board demonstrates Microchip’s MCP73831. The
MCP73831 is a miniature single-cell, fully-integrated Li-Ion/Li-Polymer
charge-management controller. A number of device options allow the MCP73831 to be
utilized in a variety of applications. Refer to the MCP73831 data sheet (DS21984) for
device options.
The MCP73831 Evaluation Kit contains two boards for evaluation of various device
options. The boards have the following features with the factory installed devices:
• Charge Voltage: 4.20V
• Programmable Fast Charge Current up to 500 mA
• Preconditioning of deeply depleted cells (MCP73831-2AC)
• No Preconditioning (MCP73831-2DC)
• Automatic Charge Termination
