MP62170ES-LF-Z

Overview

The MP62170ES-LF-Z 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 maximum current limit of 2.3 A. The device features a maximum on-resistance of 130 mΩ, a maximum turn-on time of 3 ms, and a maximum off-time of 10 ms. It functions as an active-low output switch and is rated for operation between -20°C and +85°C.

Feature Summary

• Integrates a single high-side power switch with active-low control logic for simplified interface.
• Includes internal current limiting to protect the load and switch from overcurrent conditions.
• Provides controlled turn-on and turn-off timing to manage inrush currents and system stability.

Applications

• Power distribution networks requiring single-channel switching
• Load protection circuits in embedded systems
• Peripheral power management in consumer electronics

Procurement Notes

Verify component authenticity through authorized MPS distributors or certified suppliers. Confirm the specific ES package variant matches design requirements. Check for the NRND status indicating the part is not recommended for new designs. Ensure RoHS compliance documentation aligns with regulatory needs. Validate lead times and availability directly with the manufacturer or primary agents.

Selection Notes

Select this component when a single-channel switch with 1.5 A continuous current capability is required. Ensure the input voltage stays within the 2.7 V to 5.5 V operating range. Consider the 130 mΩ on-resistance for thermal management calculations. Verify that the active-low control signal polarity matches the system logic. Evaluate the 2.3 A current limit threshold against potential fault conditions.

Part Context

This part belongs to the MPS power distribution switch family, designed for efficient power routing in low-voltage applications. It integrates protection features typically found in discrete solutions into a compact surface-mount package. The series targets cost-sensitive designs requiring reliable load switching without external protection components.

Replacement Considerations

The source data indicates the MP62170ES-LF-Z is marked as Not Recommended for New Designs (NRND). No specific public substitute part numbers are provided in the reference material. Consult MPS technical support for current alternative recommendations if redesigning.
