ZHCSIE6 June 2018 TPD6S300A
PRODUCTION DATA.
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 TPD6S300A is utilized. The TPD6S300A 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 TPD6S300A 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 |
| Dead battery charging | 100 W |
| Maximum ambient temperature requirement | 85°C |
