Product details
Overview
PTN5100DABSBZ from NXP Semiconductors is a single-port USB Type-C Power Delivery PHY and Protocol IC that implements the physical layer (BMC/4B5B/CRC) and protocol layer (packet assembly/disassembly, retries, resets) functions for USB PD 2.0 and Type-C 1.2 compliance. It operates as a dedicated UFP-role PHY co-controlled by an external policy controller MCU via SPI or I2C, supports VBUS-sourced or VDD-sourced operation, and delivers up to 30 mA to power the MCU. It is used in USB-C docking stations and mobile monitors.
For engineers reviewing the PTN5100DABSBZ datasheet, PTN5100DABSBZ pinout, PTN5100DABSBZ application, or PTN5100DABSBZ equivalent, key selection considerations include its HVQFN20 package with exposed thermal pad, open-drain FET enable outputs (EN_USBSRC/EN_USBFET1/EN_USBFET2), CC_ORIENT orientation indication, dual-mode SPI/I2C host interface, and dead-battery support via VBUS-powered operation.
Technical Context
The PTN5100DABSBZ integrates a full USB PD PHY-including slew-rate-controlled CC-line drivers, BMC encoding/decoding, 4B5B symbol conversion, and CRC generation/checking-and hardware-accelerated protocol functions including SOP packet handling, Good CRC response, hard/cable reset management, and Tx/Rx buffer control. It requires initialization by an external MCU before CC_ORIENT becomes valid.
Its architecture separates responsibilities: PTN5100DABSBZ handles timing-critical PHY tasks and register-mapped status/control, while the discrete policy controller MCU manages port policy engine, device policy manager, and alternate mode logic. The interface supports either SPI (up to 30 MHz, modes 1/2) or I2C (100 kHz–1 MHz, three slave addresses), with no simultaneous use.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C PD PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500 | Integrated policy engine; single-chip solution vs. PTN5100DABSBZ's two-chip (PHY + external MCU) architecture | Reduces MCU firmware load but limits flexibility in custom policy logic and alternate mode implementation | Choose STUSB4500 when full PD stack integration is prioritized over configurability and MCU-level control |
| TUSB7320 | USB 3.0 hub + PD PHY combo; includes integrated USB switch and 3-lane DP Alt Mode support | Targets high-bandwidth docking with native USB 3.x and video; not a standalone PD PHY like PTN5100DABSBZ | Choose TUSB7320 when combining USB data switching, video transport, and PD in one chip is required |
Compared with STUSB4500 and TUSB7320, PTN5100DABSBZ provides architectural separation of PHY and policy layers-enabling full customization of PD logic, alternate mode negotiation, and system-specific power management in the external MCU-while maintaining strict USB-IF compliance and dead-battery robustness.

FAQ
What USB specifications does the PTN5100DABSBZ comply with?
The PTN5100DABSBZ complies with USB Power Delivery specification revision 2.0 and USB Type-C Cable and Connector specification revision 1.2. It implements all mandatory PHY functions-including BMC encoding/decoding, 4B5B symbol conversion, CRC generation/checking, SOP packet framing, and hard/cable reset handling-as defined in those documents. Compliance is verified through USB-IF test procedures and supported by NXP's official certification documentation for the PTN5100DABSBZ.
How does the PTN5100DABSBZ support dead-battery operation?
The PTN5100DABSBZ supports dead-battery operation by drawing power directly from the VBUS line (3.7–25 V) instead of relying on VDD. In this mode, it powers its internal circuitry-including CC line detection, Rd termination, and CC_ORIENT orientation reporting-while delivering up to 30 mA via V_MCUPWR to boot the external policy controller MCU. This ensures full USB-C plug detection and initial PD handshake even when the host platform battery is fully depleted.
What interface options does the PTN5100DABSBZ provide for connecting to a host MCU?
The PTN5100DABSBZ provides two mutually exclusive host interfaces: SPI slave (modes 1 and 2, up to 30 MHz) or I2C slave (standard/fast/fast-plus modes: 100 kHz/400 kHz/1 MHz). The interface is factory-configured and cannot be changed in-system. I2C supports three slave addresses via SLV_ADDR pin (GND/VDDIO/open), while SPI uses fixed pin assignments (SPI_CS, SPI_CLK_I2C_SCL, SPI_MOSI_I2C_SDA, SPI_MISO) and requires no address configuration.
What is the function of the CC_ORIENT pin on the PTN5100DABSBZ?
CC_ORIENT is a CMOS output pin on the PTN5100DABSBZ that indicates USB-C cable plug orientation: LOW means normal orientation (CC1 active), HIGH means reversed orientation (CC2 active). Its polarity is inverted at power-on reset, so the external policy controller MCU must initialize the PTN5100DABSBZ via SPI or I2C before the pin level becomes valid. This enables the system to correctly route CC communication and configure alternate mode signaling.
Can the PTN5100DABSBZ operate in DFP or DRP roles?
The PTN5100DABSBZ is factory-configured as an Upstream Facing Port (UFP) and implements UFP-specific behaviors such as Rd pull-down and dead-battery detection. However, it can cooperate with an external policy controller MCU to support DFP or DRP roles at the system level-the MCU handles policy decisions while PTN5100DABSBZ provides the underlying PHY layer functions (CC signaling, BMC, packet handling) required for all roles. The IC itself does not autonomously switch roles.
