7.2.1 Design Requirements

In this application example, we study the protection requirements for a USB Type-C DRP Port, fully equipped with USB-PD, and 100W charging. The TPS2674x-Q1 is used to easily enable a DRP port. Both the CC and SBU pins are susceptible to short-to-Vbus events. With 100W charging, VBUS operates at 20V, requiring the CC and SBU pins to tolerate 20VDC. With these protection requirements present for the USB Type-C connector, the TPD4S201-Q1 is used.

The Design Parameters table lists the TPD4S201-Q1 design parameters.

Table 7-1 Design Parameters
DESIGN PARAMETER EXAMPLE VALUE
VBUS nominal operating voltage 20V
Short-to-VBUS tolerance for the CC and SBU pins 50V
VBIAS nominal capacitance 0.1µF
Dead battery charging 100W
