MCP73833EV: Li-Ion Li-Pol, 1A, Battery Charger
Summary
The MCP73833 Li-Ion Battery Charger Evaluation Board is an evaluation and demonstration tool for Microchip’s MCP73833/4 Stand-Alone Linear Li-Ion/Li-Polymer Charge Management Controllers.
The evaluation board has two circuits provided with one circuit fully assembled and tested. Each circuit is set up to evaluate simple, stand-alone, linear charging of single cell Li-Ion / Li-Polymer battery packs (the battery packs are not included). The circuits can be evaluated independently. Each circuit design provides constant current charging followed by constant voltage charging with automatic charge termination and battery temperature monitoring. In addition, the assembled MCP73833/4-FC circuit provides preconditioning of deeply depleted cells.
Each board design provides evaluation of the MCP73833/4 in two package options: a MSOP-10 (not assembled) and a 3mm x 3mm, 10-Lead DFN (assembled) for higher power handling capability.
