PTN5110THQZ

Overview

The PTN5110THQZ is a single-port USB Power Delivery (PD) Type-C Port Controller Interface (TCPC) PHY IC manufactured by NXP. It implements the Type-C Configuration Channel (CC) interface and USB PD physical layer functions to communicate with a host TCPM for policy management. The device complies with USB PD, Type-C, and TCPC specifications. It supports various Type-C roles including sink, source, DRP, and accessory modes. 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 FETs. It provides I2C-bus interface registers and state machines as defined in the TCPC specification.

Feature Summary

• Implements Type-C CC analog portion including RD/RP/RA detection and indication logic.
• Integrates USB PD TX/RX physical layer and protocol state machines compliant with TCPC standards.
• Includes an integrated VCONN load switch with programmable current limiting and thermal protection.
• Provides I2C interface for host processor control of VBUS power paths and voltage monitoring.

Applications

• Notebook PCs
• Desktop PCs
• Chromebooks
• Tablets and Convertibles

Procurement Notes

Verify the specific suffix THQZ against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target system's I2C addressing requirements, as up to four slave addresses can be selected. Confirm that the host TCPM implementation aligns with the TCPC register map and control flow defined in the datasheet.

Selection Notes

Select this component for designs requiring a standalone TCPC PHY to offload Type-C and PD handling from the main processor. It is suitable for applications needing integrated VCONN switching and VBUS discharge capabilities. Verify that the system architecture supports the required I2C communication and that the host software stack implements the necessary TCPM logic defined in the specification.

Part Context

The PTN5110 is part of NXP’s portfolio of USB Type-C and Power Delivery solutions. It complements other components such as the NX20P series for data protection and power switches. This IC focuses on the control and physical layer aspects of the Type-C interface, enabling manufacturers to build compliant USB PD sources and sinks without implementing complex analog CC circuitry or PD PHYs manually.

Replacement Considerations

Check for updated revisions or alternative packages within the PTN5110 family. Consult NXP documentation for any direct pin-to-pin replacements or upgraded versions with enhanced feature sets. Ensure any substitute maintains compliance with the same USB PD and Type-C specifications.
