Description

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 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 0.3 Ω to

minimize

signal

attenuation.
