Pin Functions

I/O

DESCRIPTION

NO.

NAME

CC2

I/O (FS)

Type-C Configuration channel signal 2. Used for connector orientation, connection detection

and removal, current capabilities, and PD communication. This pin requires an external

CRX(SHUNT) capacitor.

VBUSIN

5-24 V VBUS input voltage. Tie directly to VBUS at Type-C connector.

VDD

2.7 V to 5.5 V Positive supply voltage

VCONN

2.7 V to 5.5 V VCONN. VCONN voltage should be at a valid stable value before software

closes the VCONN switch.

INT_N

O (FS)

Open drain output. Asserted low to indicate status change occurred. Requires an external

pull-up resistor.

SCL

I/O Open-

drain (FS)

SCL - I2C communication clock signal. Requires an external pull-up resistor.

CC1

I/O (FS)

Type-C Configuration channel signal 1. Used for connector orientation, connection detection

and removal, current capabilities, and PD communication. This pin requires an external

CRX(SHUNT) capacitor.

GND

Ground

SDA

I/O Open-

drain (FS)

SDA - I2C communication data signal. Requires an external pull-up resistor.
