USB-C™ Port Controller
Overview: 

ANX7406 is a USB Type-C™ (USB-C) Port Controller that complies with the latest USB4 Version 1.0, USB Type C R2.0, and USB-PD v3.1 (r1.0) specifications. ANX7406 integrates the logic to manage cable attach and detach, orientation, and role detection. The on-chip microcontroller (OCM) facilitates USB-PD v3.0 messaging for fast charging, USB4, USB3.2, DisplayPort™ (DP) Alternate Mode (Alt Mode), and Thunderbolt3 Alternate Mode. ANX7406 can be configured as a Downstream Facing Port (DFP) or a Dual-Role Port (DRP), making it an ideal solution for various applications such as notebooks, desktops, and 2-in-1 PCs. ANX7406 supports a TCPC-compliant register interface and utilizes its 2 of I2C Slave ports for communication with an upstream embedded controller and PCH.
