∆T
1) Maximum limit specified by design.
2) VBUS_CNT = (Vth_dom +Vth rec)/2
3) VHYS = VBUSrec - VBUSdom
4) Bus load concerning LIN Spec 2.2:
Load 1 = 1 nF / 1 kΩ = CBUS / RBUS
Load 2 = 6.8 nF / 660 Ω = CBUS / RBUS
Load 3 = 10 nF / 500 Ω = CBUS / RBUS
5) Bus load
Load 1 = 1 nF / 500 Ω = CBUS / RBUS
6) Not subject to production test, specified by design.
