MP62071DH-LF-P

Overview

The MP62071DH-LF-P 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, supporting standard 3.3 V and 5 V systems. The device delivers an output current capability of 800 mA with a fixed current limit of 1.25 A. It features a maximum on-resistance of 130 mOhms for efficient power delivery. The component includes active-high control logic and provides protection against over-current conditions. It is designed for surface-mount installation in compact electronic applications.

Feature Summary

• Integrates a high-side power switch with built-in current limiting for load protection
• Features low on-resistance to minimize conduction losses and heat generation
• Supports active-high enable control for straightforward interface integration

Applications

• Power distribution in portable consumer electronics
• Load switching for USB peripheral devices
• Over-current protection in industrial control modules

Procurement Notes

Verify the specific suffix designation when ordering, as package variations exist within the product line. Confirm that the requested variant matches the required pinout and thermal characteristics for your PCB layout. Cross-reference the manufacturer's latest documentation to ensure compliance with current environmental standards and RoHS directives before finalizing procurement plans.

Selection Notes

Select this component when a single channel with moderate current capacity is required. The 130 mOhm on-resistance offers a balance between efficiency and cost. Ensure the application voltage remains within the 2.7 V to 5.5 V operational window. Consider the 1.25 A current limit threshold to guarantee adequate protection margins for the connected load without nuisance tripping during normal operation.

Part Context

This part belongs to the MPS power switch IC family focused on power distribution. It complements other variants like the MP62341 which offers dual channels. The series is designed for applications requiring reliable load switching with integrated protection features. It serves as a key component in managing power flow to downstream circuits in modern electronic systems.

Replacement Considerations

The MP62071DH-LF-Z is a verified substitute offering identical electrical specifications and functionality. Both variants share the same core performance metrics and protection features. Verify that the specific package marking or suffix does not introduce functional differences in your design implementation.
