FUSB380CUCX

Controllers Overview

The FUSB380CUCX is an autonomous USB Type-C passive cable marker manufactured by onsemi. It integrates a USB-PD 3.0 protocol layer and device policy engines within a compact 12-pin WLCSP package measuring 1.21 mm x 1.67 mm. The component supports VCONN operation from 2.4 V to 5.5 V and features 28 V tolerance on CC and VCONN pins for VBUS shorting protection. It allows field programming via Vendor Defined Messages, enabling customization of identity responses and serial numbers up to five times. The device operates within an ambient temperature range of -40°C to +85°C.
