Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
CC2 (1) 1 I/O Type-C configuration channel signal 2
CURRENT_MODE 2 I Advertise VBUS current. This 3-level input is used to control Type-C current advertisement. The pin can be dynamically set.

L - Default Current is 500 mA for USB 2.0 and 900 mA for USB 3.1. Pull-down to GND or leave unconnected.

M - Medium current is 1.5 A. Pull-up to TUSB319-Q1 VDD with 500-kΩ resistor.

H - High current is 3 A. Pull-up to TUSB319-Q1 VDD with 10-kΩ resistor.
VBUS_DET 3 I 5-V to 28-V system VBUS input voltage. One 900-kΩ external resistor required between system VBUS and VBUS_DET pin.
DIR 4 O Type-C plug orientation. This open drain output indicates the detected plug orientation: Type-C plug position 2 (H); Type-C plug position 1 (L).
ID (1) 5 O Open drain output; asserted low when the CC pins detect device attachment.
GND 6 G Ground
VDD 7 P 3.8-V to 5-V power
CC1 (1) 8 I/O Type-C configuration channel signal 1
(1) CC1, CC2 and ID pins are failsafe with leakage current defined in the Electrical Characteristics.
