MP62055EJ-LF-Z

Overview

The MP62055EJ-LF-Z is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA with a fixed current limit of 1.1 A. The device features a maximum on-resistance of 168 mΩ and utilizes a TSOT-23-5 surface-mount package. It includes active-high control logic, status reporting, and comprehensive protection mechanisms such as over-temperature shutdown, reverse current blocking, and UVLO.

Feature Summary

• Integrates active-high control logic for straightforward interface with system controllers
• Provides fault status indication through a dedicated status pin for real-time monitoring
• Includes built-in protection against over-temperature conditions and reverse current flow
• Features ultra-low on-resistance to minimize conduction losses in power distribution paths

Applications

• USB port power switching and distribution
• Peripheral device power management in portable electronics
• Load switching for low-voltage digital circuits
• Power sequencing in embedded systems

Procurement Notes

Verify the specific suffix 'LF-Z' corresponds to the tape-and-reel packaging configuration when ordering. Confirm RoHS compliance requirements align with project specifications. Ensure the TSOT-23-5 footprint matches the PCB layout design. Cross-reference the datasheet for thermal dissipation limits under expected load conditions to prevent overheating during operation.

Selection Notes

Select this component for applications requiring a single high-side switch with integrated current limiting and thermal protection. The 500 mA continuous output capability suits low-power peripheral loads. Consider the 2.7 V minimum operating voltage for compatibility with 3.3 V or 5 V systems. The TSOT-23-5 package offers a compact solution for space-constrained designs compared to larger SOIC packages.

Part Context

This part belongs to the MP62055 series of power distribution switches from Monolithic Power Systems. It is designed for efficient power management in portable devices. The series typically includes variants with different packaging options and control polarities. The MP62055 family focuses on providing robust protection features in a small form factor suitable for modern consumer electronics.

Replacement Considerations

Check for direct substitutes within the MPS MP62xxx series that match the 500 mA current rating and TSOT-23-5 package. Verify if alternative manufacturers offer comparable single-channel switches with similar electrical characteristics and protection features. Ensure pinout compatibility before substituting.
