MP62170ES-LF-P

Overview

The MP62170ES-LF-P is a single-channel power distribution switch IC 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 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 blanking time of 10 ms. It functions with active-low control logic and is rated for operation between -20°C and +85°C in an SOIC-8 package.

Feature Summary

• Integrates a single high-side power switch with active-low control logic for simplified interface design.
• Provides internal current limiting at 2.3 A to protect downstream loads from overcurrent conditions.
• Includes a programmable blanking time to prevent false triggering during startup or fault events.

Applications

• Peripheral power switching in industrial control systems
• Load distribution in automotive infotainment modules
• Power management in consumer electronics requiring 5V rail protection

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status as indicated in the datasheet. Check for end-of-life notifications such as NRND status before finalizing procurement plans. Ensure the SOIC-8 package variant matches your PCB footprint requirements.

Selection Notes

Select this component when a single-channel, low-side controlled power switch is required for 5V applications. Compare the 130 mOhms on-resistance against alternative devices to ensure acceptable power dissipation. Verify that the 2.7 V minimum operating voltage aligns with your system's logic levels. Consider the 3 ms turn-on time for applications sensitive to inrush currents.

Part Context

This part belongs to the MP621xx series of power distribution switches from Monolithic Power Systems.
