1) Load current on VCC specified positive direction out of pin.

2) Not subject to production test, specified by design.

3) Measured when the output voltage VCC has dropped 100 mV from the nominal value obtained at VS = 13.5 V.

4) Minimum limit specified by design.

5) Maximum limit specified by design.

6) VBUS_CNT =(Vth_dom +Vthrec)/2.

7) VHYS =Vth_rec -Vth_dom.

8) BUS load according to LIN Spec 2.2A:

Load 1 = 1 nF / 1 kΩ = CBUS / RLIN

Load 2 = 6.8 nF / 660 Ω = CBUS / RLIN

Load 3 = 10 nF / 500 Ω = CBUS / RLIN
