NAME

12

CC1

I/O

System side of the CC1 OVP FET. Connect to either CC pin of the CC/PD controller.

11

CC2

I/O

System side of the CC2 OVP FET. Connect to either CC pin of the CC/PD controller.

4

C_CC1

I/O

Connector side of the CC1 OVP FET. Connect to either CC pin of the USB Type-C

connector.

5

C_CC2

I/O

Connector side of the CC2 OVP FET. Connect to either CC pin of the USB Type-C

connector.

1

C_SBU1

I/O

Connector side of the SBU1 OVP FET. Connect to either SBU pin of the USB Type-C

connector. Alternatively, connect to either USB2.0 pin of the USB Type-C connector to

protect the USB2.0 pins instead of the SBU pins.

2

C_SBU2

I/O

Connector side of the SBU2 OVP FET. Connect to either SBU pin of the USB Type-C

connector. Alternatively, connect to either USB2.0 pin of the USB Type-C connector to

protect the USB2.0 pins instead of the SBU pins.

15

SBU1

I/O

System side of the SBU1 OVP FET. Connect to either SBU pin of the SBU MUX.

Alternatively, connect to either USB2.0 pin of the USB2.0 Phy when protecting the

USB2.0 pins instead of protecting the SBU pins.

14

SBU2

I/O

System side of the SBU2 OVP FET. Connect to either SBU pin of the SBU MUX.

Alternatively, connect to either USB2.0 pin of the USB2.0 Phy when protecting the

USB2.0 pins instead of protecting the SBU pins.

7

RPD_G1

I/O

Short to C_CC1 if dead battery resistors are needed. If dead battery resistors are not

needed, short pin to GND.

6

RPD_G2

I/O

Short to C_CC2 if dead battery resistors are needed. If dead battery resistors are not

needed, short pin to GND.

9
