The MCP73123-22SI/MF from Microchip Technology 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 features include constant current/constant voltage operation with thermal regulation, integrated input overvoltage protection (OVP), and a 4.15V undervoltage lockout (UVLO). The device supports battery charge voltages of 3.6V with high accuracy preset voltage regulation. Fast charge current is resistor programmable from 130 mA to 1100 mA.
Additional functionalities include preconditioning of deeply depleted cells, an integrated precondition timer, automatic end-of-charge control with selectable minimum current ratios, and automatic recharge options. The MCP73123/223 also features a soft start function and factory preset charge status output.
This controller is housed in a 10-lead DFN package (3 mm x 3 mm) with an exposed thermal pad and is suitable for surface mount applications. It operates within a temperature range of -40°C to +85°C.
