2.4.5 USB Type-C® Receptacle

Figure 2-8 shows the schematic of the USB Type-C receptacle that this design uses. From this receptacle, the communication (CC1 and CC2) and VBUS pins are mapped appropriately to the TPS25750D PD controller. In addition, the TVS2200 diode, which is a 22-V precision surge protection clamp, was also added to the design at the USB Type-C port for added protection.
