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).
