MP62340DS-1-LF-P

Overview

The MP62340DS-1-LF-P is a dual-channel, low-side power distribution switch 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 A with a current limit of 1.5 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 is housed in an 8-SOIC surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture for independent load control
• Integrated current limiting protection at 1.5 A
• Active high-side or low-side switching capability depending on configuration
• Built-in thermal shutdown and under-voltage lockout

Applications

• Power distribution in 3.3V and 5V embedded systems
• Peripheral power management in industrial equipment
• Load switching in automotive infotainment units
• Battery-powered device power gating

Procurement Notes

Verify the specific suffix 'P' indicates tube packaging when ordering from distributors. Confirm RoHS compliance status as per the latest manufacturer declaration. Ensure the SOIC-8 footprint matches your PCB design constraints. Check for moisture sensitivity level requirements during assembly. Validate that the 1A continuous current rating meets your application's peak load demands without exceeding thermal limits.

Selection Notes

Select this component for applications requiring dual-channel isolation with precise current limiting. Compare against the MP62341 series if high-side switching is preferred over low-side. Consider the 130 mΩ on-resistance for power dissipation calculations. Evaluate the 3 ms turn-on time for system startup sequencing requirements. Ensure the 2.7 V minimum operating voltage aligns with your system's brown-out conditions.

Part Context

This part belongs to the MP6234x family of power distribution switches designed for efficient load management. It complements other MPS ICs like the MP62341, which offers similar functionality but may differ in switching topology or pinout. The DS-1 variant typically denotes specific internal circuitry optimizations for standard digital loads. It serves as a robust alternative to discrete MOSFET solutions in space-constrained designs.

Replacement Considerations

The MP62341DS-LF-P is a direct functional substitute within the same product family. Verify pin compatibility and switching direction (high-side vs. low-side) before substitution. The MP62340DS-1-LF-Z is available in tape-and-reel packaging instead of tubes.
