J7 TVSP Connector
shows the J7 connector schematic. J7 is the jumper for connecting the TVSP pin to a different
resistor. The resistance between the TVSP pin and PGND determines the boot mode, USB PD port I
2
C
addresses and I
2
C logic thresholds, you can get more details through the TPS25762/72-Q1 data sheet. Default
open corresponds to EEPROM boot mode and 0x22/0x26 I2C address for port A/B. For firmware update mode,
connect a shunt on the pins 15 and 16 of J7.
In order to support USB connector pin short to VBUS or VBAT protection, it is recommended to connect an RC
circuit on TVSP pin as shown in

J8 USB2ANY Connector, J9 I
2
C MUX, and J10 Aardvark Connector
J8 and J10 are the I
2
C connectors for USB2ANY and Aardvark tools. J9 is I
2
C mux for USB2ANY and Aardvark.
The I
2
C from USB2ANY or Aardvark can be configured to connected to I
2
C1, I
2
C2, and I
2
C3. Since I
2
C bus can
support multiple slaves, it is recommended to connect all pins.
