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 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 into existing 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 0.3Ω 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.
