onsemi FUSB307B USB Type-C port controller

The FUSB307B targets system designers looking to implement up to four USB Type-C port controllers (TCPC) with USB-PD capabilities. This solution provides integrated Type-C Rev 1.3 detection circuitry, enabling manual attach/detach detection. Time-critical Power Delivery functionality is handled autonomously, offloading the µProcessor or Type-C Port Manager (TCPM). The FUSB307B complies with the USB-PD Interface Specification Rev 1.0 as a TCPC for a standardized interface with TCPM.
