(1) Typical values are given for V_SUP = 14 V at 25°C.

(2) All voltages are defined with respect to ground; positive currents flow into the TPIC1021 device.

(3) In the dominant state the supply current increases as the supply voltage increases due to the integrated LIN responder termination resistance. At higher voltages the majority of supply current is through the termination resistance. The minimum resistance of the LIN responder termination is 20 kΩ so the maximum supply current attributed to the termination is: I_SUP _{(dom) max termination} ≈ (V_SUP – (V_{LIN_Dominant}+0.7 V) / 20 kΩ.
