PI5USB2546QZHEX

Overview

The PI5USB2546QZHEX is a USB charging port controller and load detection power switch manufactured by Diodes Incorporated. It integrates a 1:1 N-channel power switch with a maximum continuous current of 2.5A, housed in a compact 16-WFQFN (3x3mm) exposed pad package. The device supports an operating supply voltage range from 2.7V to 5.5V and features low quiescent current consumption of 240uA. Designed for USB sleep charge applications, it includes built-in load detection capabilities to optimize power delivery while maintaining compatibility with standard USB interface protocols.

Feature Summary

• Integrates a high-efficiency 2.5A N-channel power switch within a single compact package
• Provides intelligent load detection functionality to manage connected device power requirements
• Supports USB sleep charge operations with ultra-low standby current consumption
• Features robust ESD protection and thermal shutdown mechanisms for reliable operation

Applications

• Mobile phone and tablet charging ports requiring integrated power switching
• USB hub designs needing per-port power management and load detection
• Consumer electronics with strict space constraints for USB connectivity
• Portable devices utilizing USB sleep charge capabilities for battery maintenance

Procurement Notes

Verify the specific suffix ZHEX confirms the reel packaging quantity and tape-and-reel format required for automated assembly processes. Ensure the W-QFN3030-16 package dimensions align with the PCB footprint design rules. Confirm RoHS compliance status through the official datasheet before finalizing procurement specifications for environmental regulations.

Selection Notes

Select this component when a combined power switch and load detection solution is required for USB ports. The 2.5A current rating suits most standard USB peripherals. Consider the 3x3mm package size for dense layouts. Verify that the 2.7V minimum operating voltage matches the system's available rail during all operational states.

Part Context

This part belongs to Diodes Incorporated's portfolio of USB interface and power management integrated circuits. It addresses the need for simplified bill-of-materials in modern mobile devices by combining switching and control functions. The product line focuses on providing compact, efficient solutions for consumer electronics manufacturers seeking to reduce component count and board space.

Replacement Considerations

Direct substitutes must match the 16-WFQFN package and 2.5A current rating. Check for equivalent load detection features if system logic depends on them. Verify pin-to-pin compatibility before replacing existing designs to avoid PCB layout modifications.
