PTN5110NDHQZ

Overview

The PTN5110NDHQZ is a USB Power Delivery (PD) Type-C Port Controller PHY IC manufactured by NXP Semiconductors. It supports Low Speed, Full Speed, and High Speed USB data rates compliant with USB 3.1 standards. The device operates on a single 3.3V supply voltage and is housed in a 16-pin HX2QFN package with an exposed pad. It functions as a TCPC PHY to manage USB Type-C connections and power delivery protocols.

Feature Summary

• Integrates USB PD protocol handling capabilities within a compact PHY interface
• Supports bidirectional data flow for Source and Sink roles via DRP functionality
• Provides hardware-level management of CC lines for Type-C port configuration

Applications

• Portable hard drive applications requiring PD consumer sink power paths
• Low-power devices such as smartphones needing 5V, 3A power delivery
• Systems utilizing buck-boost PMIC configurations for dead battery source roles

Procurement Notes

Verify the specific suffix NDHQZ against official NXP documentation to confirm pinout and electrical characteristics. Ensure compatibility with the host controller's I2C or SPI interface requirements. Confirm that the 16-pin HX2QFN package dimensions match the PCB footprint design specifications before finalizing procurement.

Selection Notes

Select this component when a dedicated USB PD PHY is required alongside a separate MCU for protocol processing. It is suitable for designs needing USB 3.1 High Speed support with integrated Type-C CC line management. Consider thermal performance due to the exposed pad requirement in the HX2QFN package layout.

Part Context

This part belongs to NXP's USB Interface ICs portfolio, specifically designed for USB Power Delivery applications. It complements other components like the CBTL08GP053EVY for high-speed signal switching. The PTN5110 series provides a standardized solution for implementing USB Type-C connectivity in consumer electronics and portable devices.

Replacement Considerations

Check for direct substitutes within the PTN5110 family, such as PTN5110DHQZ or PTN5110HQZ, which share the same package and core functionality. Verify if alternative PHY ICs from other manufacturers require significant schematic modifications.
