1. General description
PTN5150 is a small thin low power CC Logic chip supporting the USB Type-C connector
application with Configuration Channel (CC) control logic detection and indication
functions. The features of PTN5150 enable USB Type-C connector to be used in both
host and device ends of the Type-C cable. It can support Type-C to USB legacy cables
and adapters defined in USB Type-C Spec. PTN5150 can work autonomously, or can
connect to a controller through I
2
C-bus interface.
PTN5150 can be configured to dual role, host, or device mode through external
configuration pin or through I2C interface. The CC control logic detection and indication
block supports 3 current modes (default current 500 mA/900 mA, medium current 1.5 A
and high current 3.0 A) in DFP advertisement's perspective. When in UFP
advertisement's perspective, the control logic will detect if a DFP with different pull-up Rp
current source is connected. In addition, it will detect if Ra is present on CC1/CC2 pins.
Upon detection of plug orientation, pin ID will indicate if PTN5150 is working under either
host role or device role, and other status will also be reflected in I2C registers.
2. Features and benefits

USB Type-C Rev 1.1 compliance
Compatible with legacy OTG hardware and software
Support plug, orientation, role and charging current detection.
USB-ID pin for OTG application
I
2
C-bus interface support for fast mode
CC control logic detection and indication
PORT input pin to configure in DRP (Hi-Z), UFP (low) or DFP (high)
Current mode detection when PTN5150 is operating under UFP (device) role:
default current mode (<0.5 A/0.9 A); medium current mode (<1.5 A); high current
mode (<3.0 A)
