Devices Supported: MCP73831

Summary Description:

Two evaluation boards are provided in the MCP73831 Evaluation Kit. The boards are set up to evaluate simple, stand-alone, linear charging of single cell Li-Ion / Li-Polymer battery packs (the battery packs are not included). Each board design provides constant current charging followed by constant voltage charging with automatic charge termination. In addition, the MCP73831-2AC board provides preconditioning of deeply depleted cells.

Each board design provides evaluation of the MCP73831 in two package options: a SOT23-5 and a 2 mm x 3 mm, 8-Lead DFN for higher power handling capability.

Features:

• 4.2V Charge Voltage
• Programmable Fast Charge Current up to 500 mA
• Preconditioning of deeply depleted cells (MCP73831-2AC)
• No Preconditioning (MCP73831-2DC)
• Automatic Charge Termination
• Charge Current Monitor
