MP5099GDT-P

Current Regulation/Management Overview

The MP5099GDT-P is a dual-channel current limit switch with integrated current monitor, manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4.6 V to 13.8 V and supports standard 5 V and 12 V systems. The device provides independent current limiting for two channels, rated at 3 A and 4 A respectively. It features a maximum on-resistance of 65 mOhms and handles a power dissipation of 3.1 W. Designed for surface-mount installation, it is housed in a compact TQFN-10 package and functions reliably across an extended temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Dual-channel architecture with independent current limiting capabilities
• Integrated real-time current monitoring functionality
• Low on-resistance design for high efficiency
• Extended industrial operating temperature range

Current Regulation/Management Applications

• Power distribution networks requiring dual isolated rails
• Current-limited load protection in embedded systems
• Industrial equipment input stage protection
• Telecommunications infrastructure power management

Current Regulation/Management Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet before procurement. Cross-reference the specific ordering code with authorized distributors to validate availability and authenticity. Ensure the component matches the required TQFN-10 footprint and pinout configuration for your PCB layout.

Current Regulation/Management Selection Notes

Select this component when dual-channel current limiting with active monitoring is required. Compare the 3 A and 4 A channel ratings against actual load requirements to prevent unnecessary derating. Evaluate the 65 mOhm on-resistance impact on thermal performance within the system enclosure. Consider the TQFN-10 package size constraints relative to available board space and thermal pad requirements.

Current Regulation/Management Part Context

This device belongs to the MPS power switch IC family focused on power distribution applications. It complements other series like the MP5098 and MP5090 by offering specific dual-channel monitoring features. The component addresses needs for robust overcurrent protection in multi-rail systems without requiring external sensing resistors.

Current Regulation/Management Replacement Considerations

The MP5098GDT-P serves as a functional substitute within the same product family. Verify that the alternative's current limits and package compatibility meet the original design specifications.
