FUSB252: Type-C CC with High Speed Digital (HSD) Port Protection Switch

The FUSB252 is an integrated port protection switch for USB Type-C applications. This product will protect HSD+/- and CCx pins when stressed with voltages up to 20 V. Over-Voltage Protection (OVP) at 5.8 V typical will protect the system for Electrical Overstress (EOS) damage. With a fully integrated USB 2.0 switch for HSD+/-, this product can be easily integrated intoexisting solutions. The HSD switches can pass USB 2.0 signals with bandwidth 1 GHz to maintain signal integrity and eye compliance.

The CC switches have very low RON of 0.3 Ώ to minimize signal attenuation. The FUSB252 also provides Dead Battery support per the Type-C specification Additional features include Under-Voltage Lockout (UVLO) and thermal shutdown.
