FUSB3317 is a highly integrated USB Power Delivery (PD) power Source controller for USB−C that implements all functionality of USB Power Delivery 3.1 (PD) and Type−C 2.0 including Programmable Power Supplies (PPS) enabling rapid development of USB-C charging ports compliant to the latest USB requirements. The FUSB3317 directly interfaces with a DC−DC regulator removing the requirement of a load switch FET and saving PCB board space and BOM cost. FUSB3317 supports a full range of protections allowing a robust and safe implementation. These protections include adaptive Under Voltage Protection (UVP), adaptive Over Voltage Protection (OVP), Over Current Protection (OCP), CC1 and CC2 Over Voltage Protection (CCOVP), D+ and D− Over Voltage Protection (DOVP), VCONN Over Current Protection (VCONNOCP), and internal and external Over Temperature protection (ITOP and EOTP).
