PTN5100ABS：USB Type-C power delivery PHY and protocol IC, I²C

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 rail.

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 pitch.
