Overview
The MP5001DQ-LF-Z is a programmable current limit switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4 V to 10 V and supports an output current up to 5 A with a fixed current limit of 2.1 A. The device features a maximum on-resistance of 82 mOhms and handles power dissipation up to 2.5 W. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a QFN-10 surface-mount package.
Feature Summary
- Programmable current limiting capability for load protection
- Low on-resistance for efficient power distribution
- Integrated thermal and electrical protection mechanisms
Applications
- Power distribution systems requiring overcurrent protection
- Peripheral power switching in industrial equipment
- Load management in automotive electronics
Procurement Notes
Verify component authenticity through authorized channels due to the NRND status. Confirm that the QFN-10 package dimensions match design requirements. Ensure compatibility with the specified 4 V to 10 V input range. Review the datasheet for thermal management needs given the 2.5 W dissipation rating. Check for updated replacement recommendations from the manufacturer.
Selection Notes
Select this component when a single-channel power switch with adjustable current limits is required. The low on-resistance minimizes voltage drop during conduction. Verify that the 2.1 A fixed limit meets circuit safety standards. Consider the QFN-10 footprint for PCB layout constraints. Ensure the operating temperature range aligns with the application environment.
Part Context
This part belongs to the MP5001 series of power switches from Monolithic Power Systems. It is designed for high-efficiency power distribution applications. The series focuses on providing robust protection features in a compact form factor. It serves as a solution for managing power delivery to sensitive loads.
Replacement Considerations
The component is marked as Not Recommended for New Designs (NRND). Consult the official MPS documentation for specific recommended replacement part numbers before finalizing designs.
