MP5991GLU-P

Hot Swap Controllers Overview

The MP5991GLU-P is a hot-swap Intelli-Fuse controller and switch IC from Monolithic Power Systems. It features an integrated power MOSFET with 1mΩ RDS(ON), supporting up to 50A continuous output current at room temperature, or 60A with airflow. The device operates within a 4V to 16V input voltage range and includes built-in current sense, temperature monitoring, and fault protection. Packaged in LGA-32 (5mm x 5mm), it eliminates the need for external current-sense resistors or MOSFETs.

Hot Swap Controllers Feature Summary

• Integrates a low-resistance power MOSFET and driver to minimize component count
• Provides internal current mirroring and temperature sensing for precise monitoring
• Supports configurable soft-start, over-current limits, and short-circuit protection
• Includes fault signaling and health reporting capabilities for system diagnostics

Hot Swap Controllers Applications

• Hot-swap applications in server systems
• PC card insertion interfaces
• Disk drive power management
• Networking equipment backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'P' indicates the standard tape-and-reel packaging configuration when ordering. Confirm that the LGA-32 package dimensions align with your PCB footprint requirements. Ensure thermal design accounts for the specified power dissipation limits under expected airflow conditions to maintain reliability within the operating temperature range.

Hot Swap Controllers Selection Notes

Select this component for designs requiring high-current hot-swap capability without external sense resistors. The integrated 1mΩ MOSFET suits applications needing low voltage drop during insertion. Consider airflow availability if currents approach 60A, as thermal performance depends on cooling conditions. Verify compatibility with existing control logic for fault handling and soft-start timing configurations.

Hot Swap Controllers Part Context

This part belongs to the MP5991 series of Intelli-Fuse controllers. It is designed for multi-fuse hot-swap scenarios where space efficiency and integration are critical. The series supports parallel operation for higher current demands, making it suitable for dense power distribution architectures in modern electronic systems.
