PI5USB2546HZHEX

Overview

The PI5USB2546HZHEX is a USB charging port controller and power switch manufactured by Diodes Incorporated. It integrates a USB 2.0 high-speed data line (D+/D–) switch with an N-Channel power switch rated for 2.5A current. The device operates at 5V with a maximum on-resistance of 73 mOhms and consumes 270 uA operating supply current. It supports CDP/DCP modes per USB Battery Charging Specification 1.2 and Shorted Mode per Chinese Telecommunication Industry Standard. The component is housed in a 16-TQFN (3x3) package.

Feature Summary

Integrates USB charging port control, power switching, and high-speed data line switching in a single solution
Supports specific charging protocols including CDP/DCP modes and Shorted Mode compliance
Provides low on-resistance power switching capability for efficient power distribution

Applications

USB charging port controllers in mobile devices
Power distribution switches in portable electronics
Data line protection and switching in USB host or device interfaces

Procurement Notes

Verify the exact suffix 'ZHEX' against the manufacturer's official datasheet to confirm packaging type and tape/reel specifications. Ensure compatibility with the required 16-TQFN footprint and thermal requirements during integration. Cross-reference the RoHS status and lead-free markings as documented in the latest production release notes from Diodes Incorporated.

Selection Notes

Select this component when a combined solution for USB power switching and data line control is required. The integrated nature reduces board space compared to discrete solutions. Consider the 2.5A current rating and 73 mOhm on-resistance for power efficiency needs. Verify support for specific charging standards like CDP/DCP if protocol handling is part of the design requirement.

Part Context

This part belongs to the PI5USB series of USB interface and power management ICs from Diodes Incorporated. It complements other USB switches and chargers in the portfolio by offering a consolidated approach to port management. The TQFN package aligns with space-constrained consumer electronics designs requiring reliable USB connectivity and power delivery.

Replacement Considerations

The parametric equivalent listed is PI5USB2546ZHEX. Verify if the 'H' suffix denotes a specific temperature grade or package variant that impacts interchangeability. Consult the manufacturer's substitution guide to ensure functional parity regarding pinout and electrical characteristics before replacing.
