MP62170ES-1-LF

Overview

The MP62170ES-1-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 1.5 A with a current limit of 2.3 A. The device features a maximum on-resistance of 130 mOhms, a maximum turn-on time of 3 ms, and a maximum dwell time of 10 ms. It functions with active-low control logic and is rated for operation between -20°C and +85°C.

Feature Summary

• Integrates a single high-side power switch with active-low enable control for simplified interface design.
• Includes internal current limiting protection to safeguard the load and switch during fault conditions.
• Provides controlled turn-on timing to minimize inrush current effects on the power bus.

Applications

• Power distribution networks requiring single-channel switching
• Peripheral power management in embedded systems
• Load switching for low-voltage digital circuits

Procurement Notes

Verify the complete part number suffix, specifically the '-Z' designation, as it indicates lead-free compliance and specific packaging configurations. Confirm the 'NRND' (Not Recommended for New Designs) status with the manufacturer or authorized distributors before initiating procurement, as this status may impact long-term availability and support. Ensure the active-low control logic aligns with the system's microcontroller or GPIO capabilities.

Selection Notes

Select this component when a single-channel switch with 1.5 A continuous current capability is required. The 130 mOhm on-resistance determines conduction losses; verify thermal performance based on expected load currents and ambient temperatures. The active-low control logic must be compatible with the driving signal levels. Consider the -20°C minimum operating temperature if the application environment requires wider industrial ranges, as other variants may offer -40°C ratings.

Part Context

This device belongs to the MPS power distribution switch family, designed for efficient power routing in compact electronic systems. It integrates protection features typically found in discrete solutions into a small surface-mount package. The series focuses on providing reliable load switching with minimal external components, suitable for space-constrained designs requiring robust power management.
