MP5017AGD-Z

Overview

The MP5017AGD-Z is a power distribution IC from Monolithic Power Systems designed for load switching applications. It operates within an input voltage range of 3V to 5.5V and supports a continuous current capacity of 1A. The device incorporates a hard current limit set at 5A to protect downstream loads during fault conditions. Key integrated protections include an over-voltage clamp to prevent transient damage and reverse blocking functionality to ensure unidirectional current flow. The component is housed in a compact 2mm x 3mm QFN package, suitable for space-constrained designs.

Feature Summary

• Integrates over-voltage clamp protection to safeguard connected loads against input transients.
• Features reverse blocking capability to prevent backflow current when the switch is off.
• Includes a fixed 5A current limit for robust overload protection.

Applications

• Portable electronic devices requiring protected power rails
• Embedded systems with strict space limitations
• Load switching in consumer electronics

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead time requirements. Confirm the 2mm x 3mm QFN footprint matches your PCB layout constraints. Ensure the 5A current limit aligns with your system's fault tolerance needs. Check for availability as production cycles may vary. Validate that the 3V-5.5V operating range covers your application's voltage specifications.

Selection Notes

Select this component when a low-profile solution is required for 5V logic-level power distribution. The integrated over-voltage clamp eliminates the need for external TVS diodes in many scenarios. Consider the 1A continuous rating for steady-state loads and the 5A limit for short-term surge handling. The reverse blocking feature is critical if bidirectional current paths must be avoided. Evaluate thermal performance within the small QFN package for high-duty cycle applications.
