PTN5100DBSMP

Controllers Overview

The PTN5100DBSMP is a single-port USB Type-C Power Delivery PHY and Protocol IC manufactured by NXP. It provides the physical and protocol layer functions for USB PD and Type-C interfaces, interfacing with a system Policy Controller via SPI or I2C. The device supports Consumer and Consumer/Provider roles, operating from VDD (3.3 V ±10%) or directly from VBUS (up to 25 V operational, 28 V tolerant). It features an HVQFN20 package (4 mm x 4 mm) and operates within an ambient temperature range of -20 °C to +85 °C.

Controllers Feature Summary

• Complies with USB PD and USB Type-C specifications for robust interoperability.
• Supports configurable Type-C roles including UFP, DFP, and DRP implementations.
• Provides hardware-intensive USB PD PHY and Protocol functions such as BMC decoding and CRC checking.
• Includes system protection features like back current protection and high voltage tolerance on CC and VBUS pins.

Controllers Applications

• PC accessories and peripherals such as docking stations
• Mobile monitors and multi-function monitors
• Portable and external hard drives
• USB Type-C dongles and adapters

Controllers Procurement Notes

Verify the specific ordering suffix 'MP' against the official datasheet, which lists 'PTN5100DBS' as the primary type number. Confirm that the required system interface matches the factory-preconfigured option (SPI or I2C), as this setting cannot be changed post-manufacture. Ensure the policy controller MCU is compatible with the supported communication protocols.

Controllers Selection Notes

Select this component when a dedicated USB PD PHY and Protocol solution is required to offload firmware tasks from the main host processor. It is suitable for designs needing flexible role configurability and support for both battery-powered and dead-battery scenarios. Verify that the host MCU can support either SPI or I2C slave interfaces as dictated by the factory configuration.

Controllers Part Context

The PTN5100D series serves as a specialized interface bridge between USB Type-C connectors and system controllers. It handles the complex signaling and negotiation layers of USB Power Delivery, allowing system designers to implement compliant Type-C ports without integrating full PHY logic into the main application processor.

Controllers Replacement Considerations

The PTN5100DABS is a variant within the same family offering identical functionality but potentially different factory-configured interface options. Direct substitution requires verifying that the interface mode (SPI vs. I2C) matches the existing system design constraints.

Controllers FAQ

Can the PTN5100DBS operate in a dead battery condition?

Yes, the device can draw power directly from the VBUS line to operate even when the platform's internal battery is depleted or absent, provided VIO is powered.

What is the maximum voltage tolerance for the CC pins?

The CC1 and CC2 pins are rated to be 5.5 V tolerant according to the recommended operating conditions.

How is the I2C slave address determined?

The I2C slave address is programmable via the SLV_ADDR pin, which supports three combinations based on whether the pin is connected to GND, VDDIO, or left unconnected.
