Overview
The MP62131EK-LF is a single-channel power supply support circuit manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.7 V to 5.5 V and supports a maximum output current of 500 mA with a fixed current limit of 650 mA. The device features a maximum on-resistance of 130 mΩ, ensuring efficient power delivery. It is housed in an 8-pin SOIC package and functions effectively across a temperature range of -20 °C to +85 °C.
Feature Summary
- Integrates active-high control logic for precise load switching management
- Provides fixed current limiting protection to safeguard downstream components
- Includes over-temperature protection mechanisms for enhanced reliability
Applications
- Peripheral power distribution in embedded systems
- Hot-swap applications requiring controlled current limits
- Power sequencing circuits for multi-rail architectures
Procurement Notes
Verify the specific suffix (LF-Z or LF-P) against the manufacturer's latest documentation to ensure correct packaging and lead-free compliance. Confirm that the component status aligns with design requirements, as some variants may be marked as not recommended for new designs. Cross-reference the exact part number with official datasheets to validate pinout and thermal specifications before finalizing procurement orders.
Selection Notes
Select this component when a single-channel load switch with integrated current limiting is required for low-voltage applications. Ensure the operating voltage range of 2.7 V to 5.5 V matches the system rails. Consider the 130 mΩ on-resistance for power loss calculations and verify that the 500 mA continuous current rating meets the load demands without exceeding the 650 mA limit threshold.
Part Context
This part belongs to the MP62131 series of power switches from Monolithic Power Systems. It is designed for applications requiring robust protection features in a compact surface-mount package. The series typically includes variants with different suffixes indicating packaging options or qualification standards, serving as a solution for managing power distribution in portable and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints and electrical parameters if considering alternative manufacturers. Consult official MPS resources for potential cross-references or updated series replacements.
