3 Description
The TUSB320LA and TUSB320HA devices, hereafter
called TUSB320 unless otherwise noted, are Texas
Instrument's third generation Type-C configuration
channel logic and port controller. The TUSB320
devices use the CC pins to determine port attach and
detach, cable orientation, role detection, and port
control for Type-C current mode. The TUSB320
devices can be configured as a downstream facing
port (DFP), upstream facing port (UFP) or a dual role
port (DRP) making them ideal for any application.
The TUSB320 devices have an alternate
configuration as a DFP or UFP according to the
Type-C specifications. The CC logic block monitors
the CC1 and CC2 pins for pullup or pulldown
resistances to determine when a USB port has been
attached, the orientation of the cable, and the role
detected. The CC logic detects the Type-C current
mode as default, medium, or high depending on the
role detected. V_BUS detection is implemented to
determine a successful attach in UFP and DRP
modes.
The devices operate over a wide supply range and
have low-power consumption. The TUSB320 is
available in two versions of enable: Active low enable
called TUSB320LA and active high enable called
TUSB320HA. The TUSB320 family of devices are
available in industrial temperature ranges.
