Overview
The MP62341DH-LF-Z is a dual-channel power distribution switch from Monolithic Power Systems designed for 3.3V and 5V systems. It features an active-high enable input, delivering up to 1A continuous output current per channel with a 1.5A fixed current limit. The device operates within a supply voltage range of 2.7V to 5.5V and includes a maximum on-resistance of 130 mOhms. Key protection mechanisms include over-temperature shutdown, reverse current blocking, and under-voltage lockout. It utilizes an MSOP-8E package and supports a 3 ms turn-on time with a 10 ms auto-retry interval.
Feature Summary
- Dual-channel power distribution with independent high-side switching control
- Integrated fault protection including thermal shutdown and reverse current blocking
- Auto-retry mechanism restores power after fault clearance without manual intervention
Applications
- Portable electronic devices requiring efficient power routing
- Industrial equipment needing robust load protection
- Consumer electronics utilizing 3.3V or 5V logic levels
Procurement Notes
Verify the specific suffix (e.g., LF-Z) against the manufacturer's official datasheet to confirm lead-free compliance and packaging type. Ensure the order quantity matches the required reel or cut tape specifications. Confirm that the MSOP-8E package dimensions align with the target PCB footprint before finalizing procurement.
Selection Notes
Select this component when dual-channel isolation with integrated current limiting is required. The 1A rating suits moderate load applications, while the 130 mOhm resistance minimizes power loss. Consider the 2.7V minimum operating voltage for compatibility with low-power systems. Verify thermal performance requirements given the 2.3W power dissipation capability in the specified package.
Part Context
This part belongs to the MP62341 series of power switches. It serves as a specialized solution for managing multiple loads in compact spaces. The design integrates high-side MOSFETs with control logic to provide reliable power distribution. It complements other MPS PMIC offerings by focusing on simple, effective load management without complex communication interfaces.
Replacement Considerations
MP62341DS-LF-Z is a verified alternative offering identical electrical characteristics in an 8-SOIC package. Designers must verify pin-to-pin compatibility and ensure the larger SOIC footprint fits the existing layout constraints.
