MP5505EGL-P

Power Management - Specialized Overview

The MP5505EGL-P is a specialized Power Management IC (PMIC) from Monolithic Power Systems, designed as a high-efficiency energy storage and management unit for Solid State Drive (SSD) applications. It operates with a wide input voltage range of 2.7V to 7V and supports up to 4A output current. The device integrates an input current limiter with a 60mΩ MOSFET, providing up to 4.5A current limit capability. Key internal components include a 30mΩ disconnect switch and power switches rated at 70mΩ and 60mΩ. It features a 6V bus clamp voltage, adjustable dv/dt for soft-start, and over-temperature protection. The component is housed in a compact QFN-20 package measuring 3mm x 4mm.

Power Management - Specialized Procurement Notes

Verify the specific suffix GL-P against the official MPS datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status through the manufacturer's documentation. Check for obsolescence notices, as the base MP5505 model may have alternative recommendations for new designs. Ensure the QFN-20 footprint matches the PCB layout specifications provided in the ECAD models.

Power Management - Specialized Selection Notes

Select this component for applications requiring integrated energy backup without complex external circuitry. The wide input voltage range suits various single-rail supply systems. Consider the QFN-20 package size for space-constrained designs. Evaluate the need for adjustable soft-start slopes to meet specific inrush current limits. Verify that the internal power switch ratings align with the maximum load requirements of the target SSD or storage controller.

Power Management - Specialized Part Context

This part belongs to the MP series of specialized PMICs from Monolithic Power Systems. It is specifically engineered for data storage devices where power loss protection is critical. The device consolidates multiple functions into a single chip, reducing the bill of materials compared to discrete solutions. It represents a dedicated solution for managing energy transfer between the main supply and backup capacitors.

Power Management - Specialized Replacement Considerations

MPS recommends the MP5505A as an alternative for new designs. Verify compatibility regarding pinout and electrical parameters before substitution. No other direct substitutes are confirmed in public documentation.
