7.3 Design Requirements

In this application example, we study the protection requirements for a USB Type-C DRP Port, fully equipped with USB-PD, and 240W 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 240W charging, VBUS operates at 48V, requiring the CC and SBU pins to tolerate 48VDC. With these protection requirements present for the USB Type-C connector, the TPD4S480-Q1is used.

The Design Parameters table lists the TPD4S480-Q1 design parameters.

Table 7-1 Design Parameters
DESIGN PARAMETER EXAMPLE VALUE
VBUS nominal operating voltage 48V
Short-to-VBUS tolerance for the CC and SBU pins 63V
VBIAS nominal capacitance 0.1µF
Dead battery charging 240W

The recommended MOSFET settings for Q1, as shown in Table 7-2, are as follows:
