PTN5110HQZ

Overview

The PTN5110HQZ is a single-port USB Type-C Configuration Channel (CC) and Physical Layer (PHY) integrated circuit compliant with USB Power Delivery (PD), USB Type-C, and TCPC specifications. It implements the CC analog portion, including Rd/Rp/RA detection and indication, alongside PD transmit/receive PHY functions and protocol state machines for connection management. The device supports various Type-C roles such as sink, source, DRP, and accessory modes. Key integrated features include a Vconn load switch with programmable current limit, reverse leakage blocking, over-temperature protection, and two enable control outputs for managing VBUS power path FETs. It provides VBUS voltage monitoring, force discharge, and bleed discharge capabilities via an I2C interface.

Feature Summary

• Implements USB Type-C CC analog functions and USB PD physical layer protocols for connection policy management
• Integrates a Vconn load switch with programmable current limiting and thermal protection mechanisms
• Provides dual enable outputs to control external source and sink power path switches
• Supports multiple Type-C operational roles including Source, Sink, and Dual Role Power

Applications

• Notebook PCs and desktop computers
• Chromebooks and tablet devices
• Convertible laptops and docks
• Smartphones requiring low-power PD support

Procurement Notes

Verify the specific suffix 'HQZ' against official NXP documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the host TCPM firmware implementation regarding I2C register mapping. Confirm that the selected variant meets the required operating temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this component when a system requires a dedicated TCPC PHY to offload USB Type-C and PD protocol handling from the main processor. It is suitable for designs needing integrated Vconn switching and VBUS discharge controls. Verify that the host controller supports the required I2C interface speed and address configuration options defined in the specification.

Part Context

The PTN5110HQZ belongs to NXP's portfolio of USB Type-C connectivity controllers. It is part of the PTN5110 family, which serves as a foundational PHY layer for implementing USB Power Delivery compliance in consumer electronics and computing platforms. This series enables manufacturers to integrate robust Type-C port management without designing complex analog CC circuits from scratch.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Evaluate alternative NXP TCPC PHYs based on pin compatibility and feature set alignment if substitution is necessary.
