Typical values are given for VSUP = 14 V at 25°C, except for low power mode where typical values are given for VSUP = 12 V at 25°C.
All voltages are defined with respect to ground; positive currents flow into the SN65HVDA195 device.
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:
ISUP (dom) max termination ≉ (VSUP – (VLIN_Dominant + 0.7 V) / 20 kΩ
Duty cycles: LIN driver bus load conditions (CLINBUS, RLINBUS): Load1 = 1 nF, 1 kΩ; Load2 = 10 nF, 500 Ω. Duty cycles 3 and 4 are defined for 10.4-kbps operation. The SN65HVDA195 also meets these lower data rate requirements, while it is capable of the higher speed 20-kbps operation as specified by Duty cycles 1 and 2. SAEJ2602 derives propagation delay equations from the LIN 2.0 duty cycle definitions, for details see the SAEJ2602 specification.
