PTN5100 is a single port USB Type-C Power Delivery (PD) PHY and Protocol IC that provides
Type-C Configuration channel interface and USB PD Physical and Protocol layer functions
to 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 delta
updates of PD spec. This IC is targeted for a wide range of platforms (Standard Notebook
PCs, Desktop PCs, Chromebooks, Tablets, Convertibles, Smart phones) and PC Accessories
(e.g. Docks, Monitors, Cable adapters etc.) applications. PTN5100 is architected to
deliver robust performance, compliant behavior, configurability and system
implementation flexibility that are essential to tide over interoperability and
compliance 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 Facing
Port (UFP), Downstream Facing Port (DFP) or Dual Role Port (DRP) role.
PTN5100 implements VCONN low RON switch with register programmable Forward Current
protection feature. The VCON switch also provides Reverse current protection feature to
detect reverse current flow into the system whenever (inductive or) charged cable is
unplugged from the connector.
PTN5100 operates from platform power supply VDD, or it can also be powered from USB power
VBUS directly, which is especially required for operation under Dead Battery (DB)
condition and certain platform use cases. The host interface operates on VIO supply to
facilitate interfacing to systems that use IO supply rail different from VDD supply
It provides SPI/I2C interface for system host control/status update. The interface choice
is pre- configured in NXP factory.
PTN5100 is available in a small footprint package option: HVQFN20 4 mm x 4 mm, 0.5 mm
