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).
