(2) All voltages are defined with respect to ground; positive currents flow into the TPIC1021A device. (3) In the dominant state, the supply current increases as the supply voltage increases due to the integrated LIN slave termination resistance. At higher voltages the majority of supply current is through the termination resistance. The minimum resistance of the LIN slave termination is 20 k Ω, so the maximum supply current attributed to the termination is: ISUP (dom) max termination ≈ (VSUP – (VLIN_Dominant + 0.7 V) / 20 kΩ 10 Submit Documentation Feedback Copyright © 2007–2009, Texas Instruments Incorporated Product Folder Link(s): TPIC1021A-Q1 |
