MP62340DS-LF-Z

Overview

The MP62340DS-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems, designed for 3.3V and 5V systems. It operates within a supply voltage range of 2.7V to 5.5V and delivers a continuous output current of 1A per channel with a 1.5A current limit. The device features a maximum on-resistance of 130 mOhms and utilizes an active-low control type. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. It supports a power dissipation of 1.4W and functions reliably across a temperature range of -40°C to +85°C in an SOIC-8 package.

Feature Summary

• Dual-channel architecture providing independent low-side switching for two loads
• Integrated current limiting protection to safeguard connected circuits from overcurrent conditions
• Active-low control logic enabling straightforward interface with standard digital controllers

Applications

• Power distribution networks in industrial equipment
• Peripheral power management in consumer electronics
• Load switching in automotive infotainment systems

Procurement Notes

Verify the specific suffix LF-Z against official MPS documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the active-low control requirement aligns with system logic levels. Confirm moisture sensitivity handling procedures are followed during assembly to maintain component integrity.

Selection Notes

Select this component when dual isolated outputs are required within a 5.5V maximum rail. The 1A continuous rating suits moderate load applications where 130 mOhms on-resistance provides acceptable efficiency. Consider the active-low control polarity and 3ms turn-on delay relative to system startup sequencing requirements.

Part Context

This part belongs to the MP62340 series of power distribution switches. It shares the SOIC-8 footprint and core electrical characteristics with variants like the MP62341DS-LF-Z, which differs primarily in its active-high control logic. The series targets compact designs requiring integrated protection in small form factors.

Replacement Considerations

MP62341DS-LF-Z offers identical electrical performance but uses active-high control logic instead of active-low.
