MCP73831EV

The MCP73831 is an evaluation and demonstration tool for MCP73831 miniature single cell, fully integrated Li-Ion, Li-Polymer charge management controllers. 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 2mmx3mm, 8-Lead DFN for higher power handling capability.
