Product details
Overview
PTN5100ABSZ from NXP Semiconductors is a single-port USB Type-C Power Delivery PHY and Protocol IC that implements the physical layer (BMC/4B5B/CRC), protocol layer (packet assembly/disassembly, retries, resets), and CC channel interface for full PD negotiation - supporting Provider (P), Consumer (C), and Dual-Role (DRP) configurations. It integrates VCONN low-RON switch with register-programmable forward/reverse current protection, operates from VDD (3.3 V ±10%) or directly from VBUS (up to 25 V), and targets notebook PCs, docks, and monitors requiring robust USB PD compliance.
For engineers reviewing the PTN5100ABSZ datasheet, PTN5100ABSZ pinout, PTN5100ABSZ application, or PTN5100ABSZ equivalent, key selection considerations include its HVQFN20 package, SPI/I2C host interface (factory-configured), dual-role port configurability (DFP/UFP/DRP), VCONN switch capability (1 A, 2.7–5.5 V), and support for dead-battery operation via VBUS power.
Technical Context
PTN5100ABSZ implements a hardware-accelerated USB PD stack: BMC encoding/decoding, 4B5B symbol conversion, CRC generation/checking, SOP*/SOP'-debug/SOP"-debug packet handling, and autonomous CC line monitoring with orientation detection (CC_ORIENT) and debug accessory identification (DBGACC_FOUND). Its Type-C CC block applies programmable Rp/Rd termination based on NVM- or register-configured role (DFP/UFP/DRP).
The IC features three open-drain FET enable outputs (EN_USBSRC, EN_USBFET1, EN_USBFET2) for controlling external PMOS power paths, a dedicated 30 mA V_MCUPWR rail for policy controller MCU supply, and dual-power-domain operation (VDD core, VIO I/O) enabling interfacing with mixed-voltage systems. VCONN switching includes patented soft-start and real-time current monitoring for both forward (FCP) and reverse (RCP) protection.
Key Specifications

| V_MCUPWR | Policy Controller MCU Supply | Output delivering up to 30 mA at VIO voltage level; powers external PD policy engine MCU; requires 2.2 µF ceramic decoupling capacitor. |
| SPI_CLK_I2C_SCL / SPI_MOSI_I2C_SDA / SPI_CS / SPI_MISO | Host Interface Signals | Dual-function pins supporting either SPI (30 MHz) or I2C (1 MHz); SPI_CS selects device; INT_N provides active-low interrupt to MCU on event completion. |
Key Features
| Feature | Design Value |
|---|---|
| Autonomous CC Channel Operation | Hardware-based Rp/Rd termination, plug/unplug debouncing, orientation detection, and debug accessory identification - reduces MCU firmware overhead and improves response time. |
| Configurable PD Role Support | NVM- and register-programmable DFP/UFP/DRP roles with UFP pull-down for dead-battery compatibility and variable Rp for accessory detection. |
| VCONN Robustness Architecture | Patented soft-start VCONN switch with real-time forward/reverse current monitoring; disables switch and asserts interrupt on threshold violation, preventing cable-induced damage. |
| Flexible Host Interface | Factory-configured SPI or I2C interface with 3 selectable I2C addresses (via SLV_ADDR); supports mixed-voltage systems via independent VDD/VIO domains. |
| Multi-Power Domain Operation | Operates from VDD (core), VIO (I/O), or VBUS (dead-battery mode); seamless transition between supplies eliminates sequencing constraints in platform design. |
| Integrated Policy Controller Support | V_MCUPWR output powers external MCU; INT_N interrupt signals CC events, PD status changes, and protection faults - enabling deterministic, low-latency system-level control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C PD PHY and protocol applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500 | Single-port PD PHY with integrated MCU; fixed I2C interface; no VCONN switch; supports only C/P roles. | Limited to consumer/provider-only platforms; lacks autonomous CC orientation detection and VCONN protection features. | Choose STUSB4500 only for cost-sensitive, single-role applications where VCONN and DRP are not required. |
| TUSB422 | PD PHY with integrated policy engine; supports DRP but no VCONN switch; uses different register map and interrupt model. | Requires full firmware replacement; lacks reverse current protection and programmable FCP thresholds of PTN5100ABSZ. | Select TUSB422 when consolidating PHY + policy into one chip is prioritized over field-proven VCONN robustness and flexible FET control. |
Compared with STUSB4500 and TUSB422, PTN5100ABSZ offers superior system-level flexibility through its discrete policy controller architecture, hardware-enforced VCONN protection, and independent FET gate control - making it the preferred choice for high-reliability docking, monitor, and laptop platforms demanding full USB-IF certification.

FAQ
What is the primary function of PTN5100ABSZ in a USB-C system?
PTN5100ABSZ serves as the dedicated USB Type-C Power Delivery PHY and Protocol IC, handling physical layer functions (BMC/4B5B/CRC), protocol layer operations (packet assembly, retries, resets), and CC channel interface - enabling full PD negotiation while offloading complexity from the host policy controller MCU. It is not a standalone PD controller but a hardware accelerator designed to work with an external MCU.
Does PTN5100ABSZ support dead-battery operation, and how is it implemented?
Yes, PTN5100ABSZ supports dead-battery operation by drawing power directly from VBUS (up to 25 V) while maintaining full functionality of its CC interface, VCONN switch, and host interface. This is enabled via internal power domain management that allows operation with VBUS and VIO only - no VDD required - ensuring plug-in charging and port detection even when the host battery is fully depleted.
How does the VCONN switch in PTN5100ABSZ differ from basic VCONN drivers?
The PTN5100ABSZ VCONN switch incorporates patented soft-start behavior to suppress inrush current, plus register-programmable forward current protection (FCP) and reverse current protection (RCP). Unlike passive or simple-switch solutions, it actively monitors current flow in both directions and disables the switch while asserting an interrupt - preventing damage from cable unplug transients or overloads in full-featured USB-C cables.
Can PTN5100ABSZ operate in both DFP and UFP roles, and how is the role configured?
Yes, PTN5100ABSZ supports DFP, UFP, and DRP roles via NVM configuration and runtime register programming. Role selection is determined by Rp/Rd termination settings, CC line behavior, and orientation detection logic - all configurable per OEM requirements. The device implements UFP pull-down behavior specifically to meet dead-battery requirements on battery-powered platforms.
What host interface options does PTN5100ABSZ provide, and how is the interface selected?
PTN5100ABSZ supports either SPI slave (modes 1/2, up to 30 MHz) or I2C slave (100 kHz–1 MHz) interfaces - selected permanently at NXP factory during manufacturing. The interface cannot be changed in-system. I2C address is configurable via the ternary SLV_ADDR pin (GND/VDDIO/open), allowing up to three devices on one bus; SPI uses dedicated CS, CLK, MOSI/MISO, and INT_N signals.
