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). The FUSB3317 directly interfaces with a
DC−DC regulator saving the cost of a load switch FET.
FUSB3317 supports various protections, adaptive Under Voltage
Protection (UVP), adaptive Over Voltage Protection (OVP), Over
Current Protection (OCP), CC1 and CC2 Over Voltage Protection
(CC_OVP), D+ and D− Over Voltage Protection (D_OVP), VCONN
Over Current Protection (VCONN_OCP), and internal and external
Over Temperature protection (I_TOP and E_OTP).

Features
• PD 3.1 v1.0 and Type−C 2.0 Compliant
