Grounding the protection devices in USB design

ESD protection is achieved by placing a transient voltage suppression (TVS) diode between the USB port and the USB controller.

Overcurrent protection should not be used to enforce the current limits USB devices are required to meet, which is. 500mA for USB 2.0 and 950mA for USB 3.0.

The protection devices are connected from all four USB lines directly to the chassis ground, separating the ESD ground return path from the data ground.

USB 3.0 devices incorporate four additional data channels providing 5Gbps communication speeds and the power bus has been up-rated to 900mA maximum current.

The additional voltage and current introduced to the popular USB standard by USB-PD multiplies hazards and makes circuit protection essential. But des.

NX20P0477 is a single-chip USB Type-C (USB-C) port overvoltage protection solution integrating a corrosion prevention algorithm from moisture.

To properly protect the system, place the diodes as close to the source of ESD, in this case the connector, as design rules allow. USB. Controller. Power Line ...

Our portfolio of protection devices are designed with full compliance to interface standards such as USB Type-C, USB 2.0, USB 3.0, USB 3.1, HDMI and others.
