MP62181DS-LF-P

Overview

The MP62181DS-LF-P is a single-channel power distribution switch IC from Monolithic Power Systems, designed for 3.3V and 5V systems. It features a 2A continuous output current capability with a fixed 2.8A current limit. The device operates within a supply voltage range of 2.7V to 5.5V and exhibits a maximum on-resistance of 130 mOhms. Key timing parameters include a maximum turn-on time of 10 ms and a maximum idle time of 3 ms. It supports active-low control logic and includes thermal shutdown protection. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates fixed current limiting and over-temperature protection for robust load management
• Provides status flag indication to monitor operational state and fault conditions
• Supports active-low enable control for flexible system integration

Applications

• Power distribution in industrial control systems
• Load switching for peripheral devices in embedded applications
• Protection circuits in automotive electronics

Procurement Notes

Verify the NRFND (Not Recommended for New Designs) status before procurement, as this indicates the component is obsolete for new projects. Confirm that existing inventory meets long-term supply requirements if used in maintenance or legacy upgrades. Ensure compatibility with active-low control logic and SOIC-8 packaging constraints during integration planning.

Selection Notes

Select this component only for legacy designs requiring a single-channel 2A switch with active-low control. Evaluate the 130 mOhm on-resistance against thermal dissipation limits in the target application. Consider alternative MPS series if new design support is required due to the NRFND status. Verify that the 2.8A current limit aligns with load protection requirements.

Part Context

The MP62181DS-LF-P belongs to the MP6218x family of power distribution switches from Monolithic Power Systems. This series provides integrated high-side switching solutions with built-in protection features. The DS suffix denotes the SOIC-8 package variant, while the LF-P indicates lead-free compliance and reel packaging. It serves as a discrete solution for managing power delivery to individual loads.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRFND status, direct replacements may require evaluation of pin-compatible alternatives from the same manufacturer or functional equivalents with similar electrical characteristics.
