MP62341DH-LF-Z

Overview

The MP62341DH-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems. It supports input voltages from 2.7 V to 5.5 V and delivers up to 1 A continuous output current per channel. The device features a maximum on-resistance of 130 mOhms and includes a fixed current limit of 1.5 A. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. It operates within a temperature range of -40°C to +85°C and is housed in an MSOP-8E package.

Feature Summary

• Dual-channel power distribution with independent control
• Integrated active high enable logic for load management
• Built-in protection against overcurrent, overtemperature, and reverse current conditions

Applications

• Power distribution in industrial equipment
• Load switching in consumer electronics
• Peripheral power management in embedded systems

Procurement Notes

Verify the specific suffix LF-Z indicates lead-free compliance and RoHS status through official manufacturer documentation or authorized distributor datasheets. Confirm the MSOP-8E package dimensions and thermal characteristics match your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel solution is required for 3.3V or 5V systems. Ensure the 1A continuous current rating and 1.5A current limit are sufficient for the intended loads. Consider the 130 mOhm on-resistance for power dissipation calculations and verify that the 3 ms turn-on time aligns with system startup sequencing requirements.

Part Context

This part belongs to the MP62341 series of power switches. It is designed as a compact solution for managing multiple power rails in space-constrained applications. The MSOP-8E package provides a balance between pin count and thermal performance suitable for surface-mount assembly.
