DESCRIPTION
I/O
Type-C Configuration channel signal 2
I/O
Type-C Configuration channel signal 1
Tri-level input pin to indicate current advertisement in DFP (or DFP in DRP) mode while in
GPIO mode. Don’t care in UFP mode. Provides the flexibility to advertise higher current
I
without I²C. The pin has 250 K internal pull-down.
L – Low - Default – 900 mA
M - Medium (Install 500 K to VDD on the PCB) – 1.5 A
H - High (Install 10 K to VDD on the PCB) – 3 A
Tri-level input pin to indicate port mode. The state of this pin is sampled when HD3SS3220’s
ENn_CC is asserted low, and VDD is active. This pin is also sampled following a
I
I2C_SOFT_RESET.
H - DFP (Pull-up to VDD if DFP mode is desired)
NC - DRP (Leave unconnected if DRP mode is desired)
L - UFP (Pull-down or tie to GND if UFP mode is desired)
I
5-28V VBUS input voltage. VBUS detection determines UFP attachment. One 900K external
resistor required between system VBUS and VBUS_DET pin.

P
3.3-V Power supply
I/O

O
Type-C plug orientation. Open drain output.
A pull-up resistor (that is, 200 K) must be installed for proper operation of the device.
Active Low MUX Enable:
I
L - Normal operation, and
H - Shutdown.
G
Ground
