Description
The FUSB300C is a flexible, thin client solution for USB
Type-C control. This product is a generic hardware
solution that targets system designers looking to
implement a DRP/DFP/UFP USB Type-C connector
while providing the software flexibility for multiple
platform support.
The FUSB300C performs USB Type-C detection
including attach and orientation. TheFUSB300C
automates VBUS threshold detection as well as the
various charging current levels. The FUSB300C also
includes an integrated VCONN power switch.

Additionally, for Rd terminations, the software can
further determine what charging current is allowed by
the Type-C host by reading the BC_LVL status bits. This
is summarized in Table 1.

UFP Software Flow
Host Detection and Configuration
When the FUSB300C is configured as a Type-C host,
the software can use the status of the comparators and
DAC to determine when a Type-C device has been
attached or detached and what termination type has
been attached to each CC pin.
The FUSB300C allows the host software to change the
charging current capabilities of the port through the
HOST_CUR control bits. If the HOST_CUR bits are
changed prior to attach, the FUSB300C will
automatically indicate the programmed current
capability when a device is attached. If the current
capabilities are changed after a device is attached, the
FUSB300C will immediately change the CC line to the
programmed capability.
