9.2.1 Design Requirements

In this application example we study the protection requirements for a full-featured USB Type-C DRP Port, fully equipped with USB-PD, USB2.0, USB3.0, Display Port, and 100 W charging. The TPS65982 is used to easily enable a full-featured port with a single chip solution. In this application, all the pins of the USB Type-C connector are utilized. Both the CC and SBU pins are susceptible to shorting to the VBUS pin. With 100 W charging, VBUS operates at 20 V, requiring the CC and SBU pins to tolerate 20-VDC. Additionally, the CC, SBU, and USB2.0 pins require IEC system level ESD protection. With these protection requirements present for the USB Type-C connector, the TPD8S300A is utilized. The TPD8S300A is a single chip solution that provides all the required protection for the low speed and USB2.0 pins in the USB Type-C connector.

Table 2 lists the TPD8S300A design parameters.

Table 2. Design Parameters

DESIGN PARAMETER EXAMPLE VALUE
VBUS nominal operating voltage 20 V
Short-to-VBUS tolerance for the CC and SBU pins 24 V
VBIAS nominal capacitance 0.1 µF
