MP5048GU-P

Hot Swap Controllers Overview

The MP5048GU-P is a hot-swap voltage controller from Monolithic Power Systems designed for high-current applications. It features an integrated high-side MOSFET with a maximum continuous output current of 15A and an on-resistance of 7mΩ. The device operates within a supply voltage range of 24V to 60V. Key programmable parameters include current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO). It supports automatic retry and includes built-in fuse health diagnostics. The component is housed in a 30-QFN (5mm x 5mm) package and functions as a standalone Intelli-Fuse solution.

Hot Swap Controllers Feature Summary

• Integrates a high-side power MOSFET with dedicated driver circuitry for standalone operation or external controller interfacing.
• Provides precise inrush current limiting to minimize backplane voltage drops during card insertion into live systems.
• Includes comprehensive protection mechanisms such as output short-circuit protection, over-temperature protection, and fault signal output.
• Features built-in fuse health diagnostics and separate current sensing outputs for configurable over-current thresholds.

Hot Swap Controllers Applications

• Industrial equipment requiring robust hot-swap capabilities
• Server infrastructure for safe module insertion and removal
• Networking hardware utilizing standard backplane architectures

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'P' against the manufacturer's latest documentation to confirm packaging configuration and compliance status. Ensure the design accommodates the 30-QFN thermal requirements and that the 24V to 60V input range aligns with the system power rails. Confirm availability through authorized channels as lead times may vary.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution capable of handling up to 15A is required without external switching elements. It is suitable for designs needing programmable soft-start and insertion delay to manage power ramp-up. Consider parallel operation if higher current capacity beyond 15A is necessary for the specific application load.

Hot Swap Controllers Part Context

This part belongs to the MP5048 series of hot-swap controllers, which are engineered for protecting circuits during insertion into live backplanes. The series integrates power FETs and control logic to simplify design while ensuring reliable power distribution. The GU variant specifically denotes the package type and performance characteristics aligned with general-purpose industrial and networking standards.
