MP62181DH-LF-Z

Overview

The MP62181DH-LF-Z is a single-channel power distribution switch IC from Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 2 A with a current limit of 2.8 A. The device features a maximum on-resistance of 120 mOhms, a maximum turn-on time of 10 ms, and a maximum dwell time of 3 ms. It functions with active-high control logic and is housed in an MSOP-8 package. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates a high-side power switch with active-high control logic for simplified interface
• Provides robust overcurrent protection via a fixed 2.8 A current limit threshold
• Features low on-resistance to minimize conduction losses and heat generation
• Includes controlled turn-on timing to reduce inrush current stress

Applications

• Power distribution in 3.3 V and 5 V systems
• Hot-swap applications requiring controlled power sequencing
• Current-limited switching for peripheral devices

Procurement Notes

Verify the specific suffix against official documentation, as the provided data references the MP62181DD variant while the requested model uses the DH suffix. Confirm package type and pinout compatibility before integration. Check manufacturer status as this series may be marked as Not Recommended for New Designs (NRND). Ensure all electrical parameters match system requirements precisely.

Selection Notes

Select this component for single-channel load switching applications requiring 2 A continuous current. Compare the 120 mOhms on-resistance against thermal constraints. Verify that the active-high control signal aligns with the system logic levels. Consider the 10 ms turn-on time for inrush management needs. Ensure the MSOP-8 package fits the available PCB footprint.

Part Context

This part belongs to the MPS power switch IC family designed for power distribution. It serves as a protective switch element in electronic circuits. The device integrates the pass transistor and control circuitry into a compact surface-mount package. It is distinct from linear regulators or DC-DC converters, functioning specifically as a controlled switch with current limiting capabilities.
