PTN5110NTHQZ

Overview

The PTN5110NTHQZ is a single-port USB Type-C Configuration Channel (CC) and USB Power Delivery (PD) Physical Layer (PHY) integrated circuit manufactured by NXP Semiconductors. It implements the Type-C CC interface and PD physical layer functions to communicate with a TCPM that handles policy management. The device supports various Type-C roles including sink, source, DRP, and accessory modes. Key electrical features include an integrated Vconn load switch with programmable current limit, reverse leakage blocking, and over-temperature protection. It provides two enable control outputs for power path FETs and implements VBUS voltage monitoring, force discharge, and bleed discharge capabilities as defined in the TCPC specification.

Feature Summary

• Implements USB Type-C CC analog portion including RD/RP/RA detection and indication logic
• Integrates PD TX/RX PHY and protocol state machines compliant with USB PD specifications
• Includes Vconn load switch with programmable current limit and over-temperature protection
• Provides I2C-bus interface registers and finite state machines for host processor control

Applications

• Notebook PCs and desktop PCs
• Chromebooks and tablets
• Convertibles and docks
• Monitors and accessories
• Smartphones and cable adapters

Procurement Notes

Verify the specific suffix 'NQZ' against official NXP documentation to confirm package type and tape-and-reel configuration. Ensure the ordering part number matches the exact pinout and marking requirements for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with current USB Type-C and PD standards before finalizing procurement.

Selection Notes

Select this component when a system requires a dedicated PHY for USB Type-C and PD communication separate from the main controller. It is suitable for designs needing integrated Vconn switching and robust VBUS protection features without external discrete components for basic role management. Verify that the host processor supports the required I2C interface and TCPM software stack.

Part Context

The PTN5110 series serves as a bridge between the system's TCPM software and the physical USB Type-C connector. It offloads the complex analog and protocol tasks of CC line monitoring and PD packet transmission/reception from the main application processor, simplifying system design and reducing processor load in consumer electronics and computing devices.

Replacement Considerations

Direct substitutes within the same family include PTN5110DHQZ and PTN5110HQZ. These variants share identical functional specifications but may differ in packaging or environmental ratings. Confirm pin-to-pin compatibility and software register compatibility before swapping.
