MP5515 is a Wide-input 2.7V to 18V, 5A, High-Efficiency Bidirectional Power Back-Up Manager with Integrated Hot-Swap, I2C, ADC, and Cap Health Test. Utilizing MPS’ patented bidirectional single-inductor boost-buck converter for energy storage and system back-up during an input power outage event, the MP5515 has I2C function for users to perform cap health test, set current limit, and slew rate. The MP5515 can also monitor input voltage, input current, storage voltage, temperature, and provide interrupt options. This highly integrated device comes in a small 5x5mm QFN package and its back-up voltage is programmable up to 32V, designed to maximize energy storage while minimizing solution size and design effort.
