MP62340DH-LF-Z

Overview

The MP62340DH-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems, designed for 3.3V and 5V systems. It features an active-high control type with two independent outputs, each capable of delivering up to 1A continuous output current. The device incorporates a 1.5A current limit protection mechanism and exhibits a maximum on-resistance of 130 mOhms per channel. Electrical specifications include a supply voltage range of 2.7V to 5.5V, with a typical turn-on time of 3ms and a turn-off (idle) time of 10ms. It operates within a temperature range of -40°C to +85°C and is housed in an MSOP-8E package.

Feature Summary

• Dual-channel architecture providing independent control over two separate load paths
• Integrated current limiting protection to safeguard connected circuits from overcurrent conditions
• Active-high logic interface allowing straightforward digital control integration

Applications

• Power distribution networks in consumer electronics requiring dual rail management
• Industrial control systems utilizing 3.3V or 5V logic levels
• Embedded computing platforms needing isolated channel switching capabilities

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout compatibility and thermal characteristics. Ensure that the MSOP-8E package dimensions align with your PCB footprint requirements. Cross-reference the active-high control specification with your system's logic voltage levels to guarantee proper signal interfacing without additional level shifting components.

Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount form factor. The 1A per-channel rating suits moderate load applications, while the 130mOhm on-resistance helps minimize power dissipation. Consider the 2.7V minimum operating voltage if the system relies on lower-voltage rails, ensuring stable operation across the entire specified temperature range.

Part Context

This part belongs to the MP62340 series of power distribution switches. It shares functional similarities with other MPS devices like the MP62340DS-LF-Z but differs in package type and potentially control polarity. The series is designed for efficient power routing in portable and industrial devices, offering robust protection features integrated into a small footprint.

FAQ

What is the control logic polarity for the MP62340DH-LF-Z?

The MP62340DH-LF-Z utilizes an active-high control type, meaning the channels are enabled when the control input is at a high logic level.

How does the current limit protection function in this IC?

The device includes an internal current limit circuit that activates at 1.5A, protecting the load and the switch itself from excessive current draw beyond the rated 1A continuous output.
