PTN5100 is a single port USB Type-C Power Delivery (PD) PHY and Protocol IC that providesType-C Configuration channel interface and USB PD Physical and Protocol layer functionsto a System PD Port Policy Controller (Policy Engine and Device Policy Manager,Alternate mode controller). It complies with USB PD and Type-C specifications and deltaupdates of PD spec. This IC is targeted for a wide range of platforms (Standard NotebookPCs, Desktop PCs, Chromebooks, Tablets, Convertibles, Smart phones) and PC Accessories(e.g. Docks, Monitors, Cable adapters etc.) applications. PTN5100 is architected todeliver robust performance, compliant behavior, configurability and systemimplementation flexibility that are essential to tide over interoperability andcompliance hurdles in the platform applications.

PTN5100 can support system realization of the following PD roles: (i) Provider (P) only,(ii) Provider/Consumer (P/C) (iii) Consumer only (C) (iv) Consumer/Provider (C/P).Further, it can be register programmed to operate in Type-C specific Upstream FacingPort (UFP), Downstream Facing Port (DFP) or Dual Role Port (DRP) role.

PTN5100 implements VCONN low RON switch with register programmable Forward Currentprotection feature. The VCON switch also provides Reverse current protection feature todetect reverse current flow into the system whenever (inductive or) charged cable isunplugged from the connector.

PTN5100 operates from platform power supply VDD, or it can also be powered from USB powerVBUS directly, which is especially required for operation under Dead Battery (DB)condition and certain platform use cases. The host interface operates on VIO supply tofacilitate interfacing to systems that use IO supply rail different from VDD supplyrail.

It provides SPI/I2C interface for system host control/status update. The interface choiceis pre- configured in NXP factory.

PTN5100 is available in a small footprint package option: HVQFN20 4 mm x 4 mm, 0.5 mmpitch.
