NXP Semiconductors PTN5110NDHQZ

Overview

PTN5110NDHQZ from NXP Semiconductors is a single-port USB Power Delivery (PD) Type-C Port Controller (TCPC) PHY IC that implements CC analog functions, PD physical layer signaling, VCONN switching, and VBUS power path control for host TCPM coordination. It supports DRP role at power-on-reset, operates across 2.7–5.5 V core supply and 4–25 V VBUS, and delivers 8 kV HBM ESD protection in a 2.6 mm × 2.6 mm HX2QFN16 package - deployed in notebook PCs, Chromebooks, and docking stations.

For engineers reviewing the PTN5110NDHQZ datasheet, PTN5110NDHQZ pinout, PTN5110NDHQZ application, or PTN5110NDHQZ equivalent, key selection criteria include TCPC Rev 2.0 compliance, independent CC1/CC2 Rp/Rd detection, FRS_EN and ILIM_5V_VBUS GPIOs for load-switch coordination, I²C slave address flexibility (4 options), and integrated VCONN current limiting with OTP/RVP protection.

Technical Context

The PTN5110NDHQZ implements full TCPC Rev 2.0 v1.0 functionality including SOP/SOP'/SOP" packet transport, biphase mark coding, 4B5B line encoding, CRC validation, and autonomous Fast Role Swap (FRS) request detection in sink mode with indication in source mode. Its CC analog block provides dynamic Rp/Rd/Ra detection, orientation sensing, and debounced plug-in/out event generation.

It integrates dual CMOS enable outputs (EN_SRC, EN_SNK1) for discrete or load-switch-based VBUS source/sink control, supports make-before-break voltage transitions between 5 V and higher PD rails using external NX5P3290/NX20P5090 switches, and features programmable VCONN OCL thresholds, reverse leakage blocking, and fault reporting via ALERT_N/FAULT_N pins.

FAQ

What USB specifications does PTN5110NDHQZ comply with?

PTN5110NDHQZ complies with USB PD 3.0, USB Type-C 1.4, and TCPC Rev 2.0 v1.0 specifications. It implements full SOP/SOP'/SOP" packet transport, biphase mark coding, 4B5B line encoding, and CRC validation as defined in the official USB-IF documents. The PTN5110NDHQZ also supports extended messaging and chunked transport required for advanced PD features like Fast Role Swap and vendor-defined messages.

How does PTN5110NDHQZ handle VBUS voltage transitions between PD power rails?

PTN5110NDHQZ implements hardware-coordinated make-before-break sequencing for positive transitions (e.g., 5 V → 20 V) by asserting EN_SRC for the higher rail before disabling EN_SNK1 for the lower rail, with timing determined by external load switch turn-on characteristics. For negative transitions, it disables the higher rail, forces VBUS discharge, monitors voltage via internal ADC, and enables the lower rail only when VBUS reaches the target threshold. This behavior is fully implemented within PTN5110NDHQZ and requires no TCPM intervention beyond initial configuration.

What is the function of the SLV_ADDR pin on PTN5110NDHQZ?

The SLV_ADDR pin on PTN5110NDHQZ is a quaternary input sampled at power-on-reset to select one of four I²C slave addresses (1010000x to 1010011x), enabling up to four PTN5110NDHQZ devices on a shared I²C bus in multi-port systems. It must be tied to GND, pulled up to BYPASS with 10 kΩ or 100 kΩ, or left unconnected - and its state is latched only once at POR, so changes afterward have no effect. This eliminates address conflicts without requiring external EEPROM or jumpers.

Does PTN5110NDHQZ support Fast Role Swap (FRS), and how is it implemented?

Yes, PTN5110NDHQZ supports Fast Role Swap per TCPC Rev 2.0. In initial sink role, it autonomously detects FRS request signaling on the CC line and asserts the FRS_EN pin to arm the 5 V VBUS source load switch (e.g., NX5P3290). In initial source role, it indicates FRS readiness via status registers and ALERT_N. The FRS_EN pin is CMOS output referenced to BYPASS, defaults LOW at POR, and is controlled exclusively through TCPC I²C registers - no external logic is required for FRS coordination.

What protection features are integrated into the VCONN switch of PTN5110NDHQZ?

The VCONN switch in PTN5110NDHQZ integrates Reverse Voltage Protection (RVP), Over Current Limiting (OCL) with four programmable thresholds, Over Temperature Protection (OTP), and short-to-GND protection. RVP blocks reverse leakage current when disabled and triggers deglitch/retry logic upon sustained reverse bias. OCL limits current during normal operation, while OTP disables the switch above thermal threshold and auto-recovers after cooldown. All faults are reported via dedicated VCONN status bits and can generate ALERT_N interrupts for TCPM handling.
