MP62350EK-LF-P

Overview

The MP62350EK-LF-Z is a dual-channel power distribution switch from Monolithic Power Systems, designed for 3.3V and 5V systems. It features two independent outputs with a continuous current rating of 500 mA each and a peak current limit of 750 mA. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes an active-low enable control. Key electrical parameters include a maximum on-resistance of 130 mOhms per channel. It incorporates output discharge functionality and thermal protection, housed in an SOIC-8 package.

Feature Summary

• Dual-channel architecture providing independent load control for two separate circuits
• Integrated current limiting protects loads from overcurrent conditions up to the specified threshold
• Active-low enable input allows for precise system-level power management sequencing
• Built-in output discharge circuit ensures rapid removal of stored charge when disabled

Applications

• Power distribution in embedded computing systems requiring multiple voltage rails
• Peripheral interface cards needing individual channel switching and protection
• Industrial control modules managing sensor arrays or actuator groups
• Telecommunications equipment distributing power to modular sub-systems

Procurement Notes

Verify that the specific suffix EK denotes the correct tape-and-reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component lifecycle stage is acceptable for long-term production plans, as availability may vary based on manufacturing updates.

Selection Notes

Choose this component when dual independent channels are required within a single footprint constraint. The 500 mA rating suits moderate load applications without excessive heat dissipation needs. Verify that the 130 mOhm on-resistance aligns with system efficiency targets. Consider the SOIC-8 package dimensions against available PCB real estate constraints.

Part Context

This part belongs to the MP62350 series of power distribution switches. It shares functional similarities with other MPS devices like the MP6231 but offers enhanced features such as integrated output discharge. The series is targeted at applications requiring reliable power routing with built-in protection mechanisms for sensitive electronic loads.

Replacement Considerations

Direct substitutes include the MP6231 series variants which offer similar dual-channel capabilities. Cross-reference pinouts and electrical specifications carefully to ensure compatibility with existing board layouts and thermal requirements.
