FUSB302B
FUSB302B Programmable
USB Type‐C Controller w/PD
Description
The FUSB302B targets system designers looking to implement
a DRP/SRC/SNK USB Type-C connector with low amount of
programmability.
The FUSB302B enables the USB Type-C detection including
attach, and orientation. The FUSB302B integrates the physical layer
of the USB BMC power delivery protocol to allow up to 100 W of
power and role swap. The BMC PD block enables full support for
alternative interfaces of the Type-C specification.

Description
USB TYPE-C CONNECTOR INTERFACE
CC1/CC2
I/O
Type-C connector Configuration Channel (CC) pins. Initially used to determine when an attach has
occurred and what the orientation of the insertion is. Functionality after attach depends on mode of
operation detected.
Operating as a host:
1. Sets the allowable charging current for VBUS to be sensed by the attached device
2. Used to communicate with devices using USB BMC Power Delivery
3. Used to detect when a detach has occurred
Operating as a device:
1. Indicates what the allowable sink current is from the attached host. Used to communicate with
devices using USB BMC Power Delivery
Ground
VBUS input pin for attach and detach detection when operating as an upstream facing port
(Device). Expected to be an OVP protected input.
