Specifications

The FUSB3601UCX operates from a supply voltage of 3V to 5.5V and supports USB Power Delivery up to 100W. It uses an I2C interface for configuration and control by the host processor. It includes integrated protection features such as over-voltage protection (OVP) and over-current protection (OCP). It is typically packaged in a small form factor such as a WLCSP (Wafer Level Chip Scale Package) for space-constrained applications. It manages cable orientation detection and role detection according to USB Type-C specifications.
