PTN5110NHQZ

Overview

The PTN5110NHQZ is a single-port USB Power Delivery (PD) TCPC PHY IC designed to implement Type-C Configuration Channel (CC) interface and USB PD Physical layer functions. It complies with USB PD, Type-C, and TCPC specifications, targeting system platforms such as notebooks, tablets, and smartphones. The device supports Sink, Source, and Dual Role Port (DRP) roles, including Provider/Consumer configurations. Key features include integrated VCONN load switch with programmable current limit, reverse leakage blocking, and over-temperature protection. It provides two enable control outputs for VBUS source/sink power paths and implements VBUS voltage monitoring, force discharge, and bleed discharge. The IC communicates via an I2C-bus interface supporting standard, fast, and fast mode plus speeds.

Feature Summary

• Supports Type-C CC analog functions including dynamic Rp/Rd/Ra detection and independent pull-up resistor implementations on CC1 and CC2 pins.
• Integrates VCONN load switch with reverse voltage protection, over-current limiting, and over-temperature protection.
• Provides VBUS power path control outputs (EN_SRC, EN_SNK1) and supports seamless voltage transitions between PD rails.
• Features up to four selectable I2C slave addresses for multi-port implementation flexibility.

Applications

• Notebook PCs, Desktop PCs, Ultrabooks, and Chromebooks
• Tablets, 2:1 Convertibles, Smartphones, and Portable devices
• Docking stations, Mobile Monitors, and Multi-Function Monitors
• Portable/External hard drives, Cable adaptors, and Dongles

Procurement Notes

Verify the specific ordering suffix NHQZ corresponds to the TCPC Rev 2.0 version 1.0 configuration. Confirm that the DRP toggle starting state is set for Sink (Rd) role at power-on reset. Ensure compatibility with the required HX2QFN16 package dimensions and thermal requirements for the target PCB layout.

Selection Notes

Select this part when a TCPC Rev 2.0 compliant PHY is required for DRP applications starting in the Sink role. It is suitable for systems needing integrated VCONN switching and robust power path control. Consider alternative suffixes like DHQZ or THQZ if fixed Sink or Source roles are preferred instead of dual-role operation.

Part Context

The PTN5110 series includes variants such as PTN5110HQ, PTN5110DHQ, and PTN5110THQ, which support TCPC Rev 1.0. The PTN5110NHQZ specifically adheres to TCPC Rev 2.0. All variants share the same HX2QFN16 package but differ in default power-on reset roles and protocol compliance versions.
