Functional Pin Description

Pin No.

Pin Name

Pin Function

1

ADR

Address selection node when used with multiple type-C ports.

2

EN

External power path control input, active-high.

3

VCC

Input supply voltage.

4

VTUNE

Connected to FB pin of a DC-DC converter to adjust DC-DC output voltages.

5

GP2

High voltage open-drain gate driver, which may be used to drive an NMOS/PMOS

power switch. This pin is connected to the gate of the power switch. (Related to

VDC).

6

GP3

High voltage open-drain gate driver, which may be used to drive an NMOS/PMOS

power switch. This pin is connected to the gate of the power switch. (Related to

VDC).

7

VDC

Barrel jack or wireless charger DC power input pin for charging path control.

8

CC2

Type-C connector Configuration Channel (CC) 2, used to detect a cable plug event

and determine the cable orientation.

9

VCONN

Regulated input voltage to power CCx pins as VCONN.

10

CC1

Type-C connector Configuration Channel (CC) 1, used to detect a cable plug event

and determine the cable orientation.

11

VBUS

VBUS input using for OCP/OVP detection and as a power source for VBUS path

control.

12

CS

Current sense input.

13

GP1A

High voltage open-drain gate driver, which may be used to drive an NMOS/PMOS

power switch. This pin is connected to the gate of the power switch. (Related to

VBUS).

14

GP1B

High voltage open-drain gate driver, which may be used to drive an NMOS/PMOS

power switch. This pin is connected to the gate of the power switch. (Related to

VBUS).

15

NC

No internal connection.

16,

25 (Exposed Pad)

GND

Ground. The exposed pad must be connected to GND and well soldered to a large

copper PCB and for maximum power dissipation.

17

SCL

I2C interface serial clock input. Open-drain. An external pull-up resistor is required.

18

SDA

I2C serial data input/output. Open-drain. An external pull-up resistor is required.

19

INT_N

Interrupt output, active-low open-drain, to prompt the processor to read the

registers.
