It may be necessary to incorporate an ESD component to protect the TUSB522P from electrostatic discharge (ESD). It is recommended that the ESD protection component has working peak voltage of ≥ 1.3 V, a breakdown voltage of ≥ 2.3 V, and a clamp voltage of ≤ 4.0 V. A clamp voltage greater than 4.0 V may require a R_ESD on each differential pin. The ESD component should be placed near the USB connector.
