PTN5100ABSZ

Controllers Overview

The PTN5100ABSZ is a single-port USB Type-C Power Delivery PHY and Protocol IC manufactured by NXP USA Inc. It provides the Configuration Channel interface and handles USB PD Physical and Protocol layer functions for system Policy Controllers. The device supports Provider (P), Consumer (C), and combined P/C roles, with register-programmable Type-C role configurability including Upstream Facing Port (UFP), Downstream Facing Port (DFP), and Dual Role Port (DRP). It features a low RON VCONN switch capable of delivering up to 1 A between 2.7 V and 5.5 V, along with forward and reverse current protection. The IC operates from VDD or VBUS supplies, supports SPI/I2C host interfaces, and is housed in an HVQFN20 package.

Controllers Feature Summary

• Implements USB PD PHY and Protocol layers compliant with specifications, handling BMC/4B5B coding, CRC, and packet assembly.
• Integrates a low RON VCONN switch with programmable forward and reverse current protection capabilities.
• Provides dedicated gate control signals for external PMOS power MOSFETs on VBUS source and sink paths.
• Supports autonomous CC detection and orientation indication via hardware circuitry.

Controllers Applications

• PC platforms such as Notebook PCs, Desktop PCs, Ultrabooks, and Chromebooks
• Tablets, 2:1 Convertibles, Smartphones, and portable devices
• PC accessories including docking stations, mobile monitors, and cable adaptors

Controllers Procurement Notes

Verify the specific ordering suffix 'ABS' against the manufacturer's documentation to confirm factory-configured interface settings. Ensure the procurement channel sources components from authorized distributors to guarantee authenticity. Check the latest datasheet revision for any updates to electrical characteristics or pin definitions prior to finalizing orders.

Controllers Selection Notes

Select this component when a dedicated USB Type-C PD PHY and Protocol solution is required to offload processing from the main MCU. It is suitable for designs needing flexible role configurability and robust VCONN switching. Verify that the system host controller supports either SPI or I2C communication protocols, as only one interface can be active at a time based on factory configuration.

Controllers Part Context

The PTN5100 series serves as a specialized interface bridge between USB Type-C connectors and system policy controllers. It simplifies compliance with USB PD standards by handling complex physical layer signaling and protocol state machines. This allows system designers to focus on higher-level power management logic while relying on the IC for reliable connection detection and power negotiation support.

Controllers Replacement Considerations

PTN5100BS is a compatible variant within the same family. Confirm if the factory-configured interface selection differs between the ABS and BS suffixes before substitution.

Controllers FAQ

Can the PTN5100 operate without a battery present?

Yes, the device supports Dead Battery operation by drawing power directly from the VBUS supply rail.

What types of host interfaces are supported?

The IC supports both SPI slave and I2C slave interfaces, though only one can be used per device based on factory configuration.

How does the device handle VCONN current protection?

It implements programmable Forward Current Protection and Reverse Current Protection to safeguard the VCONN switch and system.
