Overview
The MP62171EK-1-LF-Z is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1.5 A with a fixed current limit of 2.3 A. The device features a maximum on-resistance of 130 mΩ, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. It functions in an active-low configuration and is rated for operation between -20°C and +85°C.
Feature Summary
- Integrates a high-side power switch with built-in overcurrent protection capabilities.
- Provides low on-resistance for improved efficiency in power distribution applications.
- Features active-low control logic for straightforward interface with system controllers.
Applications
- Power distribution networks in portable electronic devices
- Load switching for peripheral components in consumer electronics
- Protection circuits in industrial control systems
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before finalizing procurement plans. Confirm that the TSSOP-8 package variant aligns with existing PCB footprints. Ensure supply chain sources provide authentic Monolithic Power Systems documentation to validate specifications against potential counterfeit risks.
Selection Notes
Select this component when a single-channel load switch with 1.5 A capacity is required for 5 V systems. Consider the 130 mΩ on-resistance for thermal management requirements. Evaluate the 2.3 A current limit threshold against peak load transients to ensure adequate protection margins without nuisance tripping during normal operation.
Part Context
This part belongs to the MP6217x family of power switches from MPS. It shares architectural similarities with the MP62170EK-1-LF-Z but may differ in specific pinout configurations or packaging options. The EK suffix typically denotes a specific tape-and-reel packaging format intended for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official MPS resources for cross-reference recommendations if this NRND component requires replacement in existing designs.
