MCP73833EV

The MCP73833EV is an evaluation and demonstration tool for MCP73833/4 stand alone linear Li-Ion/Li-Polymer charge management controllers. Two independent circuits are provided (only one is populated) for charging single cell Li-Ion / Li-Polymer battery packs (the battery packs are not included). Each circuit design provides constant current charging followed by constant voltage charging algorithm with automatic charge termination and battery temperature monitoring. In addition, the installed MCP73833-FCI/MF provides preconditioning of deeply depleted cells and a safety timer. The MCP73833 evaluation board provides for evaluation of the MCP73833/4 in two package options a MSOP 10 (not populated) and a 3mm x 3mm, 10 Lead DFN for higher power handling capability (MCP73833-FCI/MF installed). When connected, this evaluation board allows for the evaluation of the MCP73833/4 devices in a variety of applications.
