USB Type-C Port Controller (TCPC)
Overview
TCPC (USB Type-C Port Controller) The TCPC is a device used to simplify the implementation of a USB-C system by providing the following three function:
VBUS and VCONN control USB Type-C: The TCPC may provide a Source device, the mechanism to control VBUS sourcing, and a Sink device, the mechanism to control VBUS sinking. A similar mechanism is provided for the control of VCONN.
CC control and sensing: The TCPC implements logic for controlling the CC pin pull-up and pull-down resistors. It also provides a way to sense and report what resistors are present on the CC pin.
Power Delivery message reception and transmission USB Power Delivery: The TCPC sends and receives messages constructed in the TCPM and places them on the CC lines.
TCPC API
The TCPC device driver functions as the liaison between the TCPC device and the application software; this is accomplished by the Zephyr’s API provided by the device driver that’s used to communicate with and control the TCPC device.
