MCP73833 Li-Ion Battery Charger Evaluation Board

Part Number: MCP73833EV

The MCP73833 Evaluation Board is an evaluation and demonstration tool for Microchip’s 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).

    • Charge Voltage: 4.20V
    • Programmable Fast Charge Current up to 1000mA
    • Preconditioning of deeply depleted cells
    • Automatic Charge Termination
    • Automatic Recharge
    • Battery Temperature Monitor
    • Safety Timer
    • Thermal Regulation
    • Reverse Discharge Protection
