Overview
The MP5018GD-P is a single-channel power distribution switch IC from Monolithic Power Systems, designed for 5V systems. It features a programmable current limit ranging from 1A to 5A and operates within a supply voltage range of 4.5V to 5.5V. The device is housed in a QFN-12 surface-mount package and supports an operating temperature range from -40°C to +125°C. It includes reverse current blocking functionality to prevent backflow.
Feature Summary
- Programmable current limiting capability allows customization between 1A and 5A thresholds.
- Integrated reverse current blocking prevents backward flow from output to input.
- High thermal performance supports operation up to +125°C ambient temperature.
Applications
- Power distribution in 5V embedded systems
- Peripheral protection in industrial control units
- Current limiting for high-side load switching
Procurement Notes
Verify the specific current limit setting required for your application against the datasheet programming guidelines. Confirm that the QFN-12 footprint matches your PCB layout. Ensure the supply voltage remains strictly within the 4.5V to 5.5V operational window to maintain device integrity and performance specifications.
Selection Notes
Select this component when a single-channel solution with adjustable current protection is needed for 5V rails. It is suitable for applications requiring reverse blocking without external diodes. Consider the QFN-12 package size constraints and thermal dissipation requirements relative to the maximum programmed current limit before finalizing the design.
Part Context
This part belongs to the MPS MP5018 series of power switches. It is distinct from higher-voltage variants like the MP5014 or multi-channel devices such as the MP5092. The GD suffix indicates the specific pinout and package configuration compatible with standard QFN-12 footprints.
Replacement Considerations
Direct substitutes include other MPS single-channel 5V switches with similar current limits, such as the MP5017AGD-P, provided the voltage and current ratings align with system requirements.
