8.3.4 Ground (GND)

This is the TPIC1021 device ground connection. The TPIC1021 operates with a ground shift as long as the ground shift does not reduce VSUP below the minimum operating voltage. If there is a loss of ground at the ECU level, the TPIC1021 does not have a significant current consumption on the LIN pin while in the recessive state (<100 µA sourced via the LIN pin) and for the dominant state the pull-up resistor should be active.
