MP62131ES-LF-Z

Overview

The MP62131ES-LF-Z is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.7 V to 5.5 V and provides a maximum output current of 500 mA with a fixed current limit of 650 mA. The device features a maximum on-resistance of 130 mΩ, ensuring efficient power delivery. It is housed in an 8-pin SOIC package and supports active-high control logic. The component functions reliably across an operating temperature range from -20 °C to +85 °C.

Feature Summary

• Integrates a high-side power switch with built-in current limiting protection for load circuits.
• Features low on-resistance to minimize conduction losses and heat generation during operation.
• Includes internal circuitry for controlled turn-on and turn-off timing to manage inrush currents.

Applications

• Power distribution networks in portable electronic devices
• Peripheral interface protection in consumer electronics
• Battery-powered equipment requiring regulated power switching

Procurement Notes

Verify the specific suffix LF-Z confirms lead-free compliance and RoHS status before procurement. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Check the manufacturer's latest documentation for any design-in restrictions or updated thermal guidelines associated with this discontinued part number.

Selection Notes

Select this component when a single-channel, 500 mA rated power switch is required for 3.3 V or 5 V systems. Ensure the application does not exceed the 650 mA current limit threshold. Consider the 130 mΩ on-resistance impact on total system efficiency and thermal management capabilities within the specified ambient temperature range.

Part Context

This part belongs to the MPS power distribution switch family designed for protecting loads in low-voltage applications. It serves as a discrete solution for managing power rails where integrated circuit protection is necessary. The device replaces older discrete MOSFET solutions by combining switching and protection functions in a compact surface-mount package.

Replacement Considerations

The manufacturer lists this component as NRND (Not Recommended for New Designs). Engineers should consult official substitution guides for equivalent current-limited switches with similar voltage ratings and package footprints.
