Monolithic Power Systems, Inc. Power Management - Specialized MP5515GU-P

The MP5515GU-P is a power management integrated circuit (PMIC) designed for enterprise solid-state drives (SSDs), NVDIMMs, and backup systems. It features a wide input voltage range of 2.7V to 18V and can handle up to 5A of buck load capability. The device incorporates a high-efficiency, bidirectional boost-buck converter that utilizes a single inductor for energy storage, enabling backup power during input outages. Key functionalities include input current limiting, reverse current protection, and an I¬=C interface for configuration and monitoring. The MP5515GU-P allows users to set input current limits, adjust slew rates, and perform capacitor health tests. It also provides comprehensive monitoring of system parameters such as input voltage, current, storage voltage, and temperature, along with interrupt options for these features. The device is packaged in a compact 30-pin QFN (5mm x 5mm) format and requires minimal external components, making it suitable for space-constrained applications. Its robust protection features, including input over-voltage protection and thermal shutdown, enhance reliability in demanding environments.
