The MCP73223-C2SI/MF-ND is a highly integrated Lithium Iron Phosphate (LiFePO4) battery charge management controller designed for space-limited and cost-sensitive applications. It features integrated input overvoltage protection, a pass transistor, current sense, and reverse discharge protection. The device operates with a constant current/constant voltage charge algorithm and includes thermal regulation to optimize charge cycle time while ensuring reliability. This controller supports a maximum input voltage of 13V and offers a high accuracy preset voltage regulation of ¬±0.6% across a temperature range of -5¬8C to +55¬8C. The MCP73223 allows for programmable fast charge currents ranging from 130 mA to 1100 mA and includes options for preconditioning deeply depleted cells. It also features an automatic end-of-charge control with selectable minimum current ratios and an elapse safety timer. The MCP73223-C2SI/MF-ND is suitable for various applications, including low-cost LiFePO4 battery chargers, power tools, toys, and backup energy storage solutions. It is packaged in a compact DFN-10 (3 mm x 3 mm) format, making it ideal for designs where space is a constraint.
