The Microchip Technology MCP73223-C2SI/MF is a highly integrated Lithium Iron Phosphate (LiFePO4) battery charge management controller designed for space-limited and cost-sensitive applications. It provides specific charge algorithms for LiFePO4 batteries to optimize capacity and safety.
Key electrical features include a programmable fast charge current ranging from 130 mA to 1100 mA, with a maximum of 1.1A. The device supports battery pack voltages up to 7.2V and operates with 1 to 2 cells. It includes features like constant current/constant voltage operation with thermal regulation, undervoltage lockout (UVLO) at 4.15V, and selectable preconditioning and recharge options.
This controller is designed for harsh environments with an absolute maximum input voltage of 18V. It operates reliably within a temperature range of -40°C to +85°C. The MCP73223-C2SI/MF is housed in a compact 10-lead DFN package with an exposed thermal pad, suitable for surface mounting.
Applications for this charge controller include low-cost LiFePO4 battery chargers for power tools, toys, and backup energy storage solutions. Its small size and low external component count make it ideal for various integrated designs.
