MP62071DH-LF

Overview

The MP62071DH-LF-Z is a single-channel power distribution switch IC from Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 800 mA with a fixed current limit of 1.25 A. The device features a maximum on-resistance of 130 mOhms, ensuring efficient power delivery. It includes timing controls with a maximum on-time of 3 ms and off-time of 10 ms. The component is designed for surface-mount installation in MSOP-8 packages and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates active-high control logic for straightforward interface with system controllers
• Provides built-in current limiting protection to safeguard connected loads from overcurrent conditions
• Features low on-resistance MOSFET architecture to minimize conduction losses and heat generation

Applications

• Power distribution switching in portable electronic devices
• Load management in industrial control systems
• Peripheral power gating in consumer electronics

Procurement Notes

Verify the specific suffix (e.g., LF-Z) against official MPS documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm compatibility with your design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single high-side switch with moderate current capability is required. The 800 mA continuous rating suits applications where load currents remain below the 1.25 A hard limit. Consider the 130 mOhm Rds(on) for thermal management calculations. Verify that the 2.7 V minimum supply voltage aligns with your system's available rail during all operating conditions.

Part Context

This device belongs to the MP6207x series of power distribution switches. It shares architectural similarities with other members like the MP62341 but differs in channel count and current ratings. The series focuses on providing compact solutions for power gating in space-constrained designs. It complements MPS's broader portfolio of PMICs by offering discrete switching functionality without complex regulation requirements.

Replacement Considerations

Direct substitutes include the MP6211DH-LF-P for similar single-channel applications, though output current ratings differ. The MP62341DH-LF-Z offers dual-channel capability with comparable voltage ranges. Verify pinout compatibility and thermal performance characteristics when transitioning between these variants to ensure seamless integration into existing hardware designs.
