MP5048AGU-Z

Hot Swap Controllers Overview

The MP5048AGU-Z is a hot-swap voltage controller from Monolithic Power Systems designed for network applications. It operates within a supply voltage range of 24V to 60V and supports a maximum output current of 5A. The device features an integrated internal switch with a typical on-resistance of 14mΩ. It is housed in a 30-QFN (5x5) surface-mount package and functions reliably across a junction temperature range of -40°C to +125°C.

Hot Swap Controllers Feature Summary

• Integrates an internal power switch for compact board space utilization
• Supports programmable current limiting, fault timeout, overvoltage protection, and UVLO
• Includes automatic retry and latch-off fault protection mechanisms
• Enables communication via PMBus interface for advanced control

Hot Swap Controllers Applications

• Network infrastructure equipment
• Telecommunications systems
• Industrial control panels

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official datasheets to confirm functional differences, as ordering codes may indicate variations in packaging or revision status. Confirm RoHS compliance and environmental declarations prior to integration. Ensure the selected package matches the PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability.

Hot Swap Controllers Selection Notes

Select this component when a single-channel hot-swap solution with integrated switching capability is required for high-voltage input rails. The inclusion of PMBus allows for digital monitoring and configuration, distinguishing it from basic analog controllers. Consider the thermal performance of the QFN-30 package relative to the expected load current and ambient conditions during system design.

Hot Swap Controllers Part Context

This device belongs to the MP5048 family of hot-swap controllers, which are engineered for protecting circuits during insertion into live backplanes. The AGU variant specifically denotes the 30-QFN package style. It serves as a critical power distribution element, preventing damage from inrush currents and short circuits in sensitive electronic modules.
