PTN5110DHQZ

Overview

The PTN5110DHQZ is a single-port USB Power Delivery (PD) Type-C Port Controller Protocol (TCPC) PHY IC manufactured by NXP Semiconductors. It implements the Type-C Configuration Channel (CC) interface and USB PD physical layer functions to communicate with a host TCPM that manages policy. The device complies with USB PD, Type-C, and TCPC specifications. It supports various Type-C roles including sink, source, dual-role port (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 power path management. It also provides VBUS voltage monitoring, force discharge, and bleed discharge capabilities via an I2C-bus interface.

Feature Summary

• Integrates Type-C CC analog portion for RD/RP/RA detection and indication alongside full USB PD TX/RX PHY and protocol state machines.
• Includes an internal VCONN load switch featuring programmable current limiting, reverse leakage current blocking, and over-temperature protection.
• Provides hardware control outputs for managing VBUS source and sink power paths, along with VBUS voltage monitoring and discharge features.

Applications

• Portable hard drive applications utilizing PD consumer sink power paths
• Notebook PCs and desktop PCs requiring Type-C connectivity
• Chromebooks and tablet devices supporting USB Power Delivery
• Docks, monitors, and cable adapters implementing Type-C interfaces

Procurement Notes

Verify the specific suffix DHQZ against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component version matches the required revision for your design. Cross-reference the ordering part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a system requires a dedicated TCPC PHY to offload Type-C and USB PD physical layer processing from the main processor. It is suitable for designs needing integrated VCONN switching and precise VBUS monitoring without external PHY components. Verify that the host TCPM implementation aligns with the I2C register map and control flow defined in the specification.

Part Context

The PTN5110 series serves as a foundational interface controller for USB Type-C implementations within NXP's peripheral portfolio. It bridges the gap between the physical Type-C connector and the system's application processor or microcontroller. This family enables compliance with evolving USB-IF standards while reducing board space and component count for power delivery applications.

Replacement Considerations

Check for updated revisions of the PTN5110 series or compatible TCPC PHYs from NXP such as the PTN5150 if higher integration is required. Verify pin-to-pin compatibility and I2C register mapping before substituting with other manufacturers' devices to ensure protocol compliance.
