Overview
The MP5001DQ-LF-P is a programmable current limit switch from Monolithic Power Systems designed for power distribution applications. It operates within a supply voltage range of 4 V to 10 V and supports output currents up to 5 A. The device features a maximum on-resistance of 82 mΩ and includes a programmable current limit set at 2.1 A. Housed in a QFN-10 surface-mount package, it functions across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates programmable current limiting functionality for precise load protection
- Provides low on-resistance for efficient power distribution with minimal voltage drop
- Supports single-channel output configuration for targeted circuit management
Applications
- Power distribution networks requiring adjustable overcurrent protection
- System-level power switching for peripheral devices
- Industrial control circuits operating within specified voltage ranges
Procurement Notes
Verify component authenticity through authorized channels due to the NRND status. Confirm that the QFN-10 package dimensions align with PCB layout requirements. Ensure thermal management strategies accommodate the operational temperature limits. Validate that the programmable current threshold meets specific load protection criteria before integration.
Selection Notes
Select this component when a single-channel power switch with adjustable current limiting is required. Consider the 4 V to 10 V input range compatibility with system rails. Evaluate the 82 mΩ on-resistance against efficiency targets. Verify that the QFN-10 footprint fits the design constraints and that the -40°C to +85°C range suits the environment.
Part Context
This part belongs to the MPS power switch IC family focused on power distribution. It serves as a protective element between power sources and loads. The device replaces traditional discrete solutions by integrating switching and protection logic. It is distinct from linear regulators and audio amplifiers offered by the manufacturer.
Replacement Considerations
The component is marked as Not Recommended for New Designs (NRND). Engineers should identify alternative current limit switches or power distribution ICs with updated availability. Cross-reference specifications such as on-resistance, current limit range, and package type to ensure functional equivalence in new projects.
