4

CC1

AIO

Configuration line 1 used to negotiate a voltage/current with the attached adapter.

5

CC2

AIO

Configuration line 2 used to negotiate a voltage/current with the attached adapter.

6

SDA

DIO

I2C communication data signal.

7

SCL

DIO

I2C communication clock signal.

8

VSET

AI

Connect a resistor to indicate the maximum voltage needed by the system from the

attached power adapter.

9

ISET

AI

Connect a resistor to indicate the maximum current needed by the system from the

attached power adapter.

10

GATE

OD

Open drain gate driver output. Connect this signal to the gate of an external PMOS

through a series resistor. Leave this pin open if not used.

11

GND

P

Ground reference. All signals are referred to this pin.
