Parameters
Pull-up resistor to V
Voltage drop at the serial
diodes
LIN current limitation
V
Input leakage current at
the receiver including
pull-up resistor as
specified
Leakage current LIN
recessive
Leakage current when
control unit disconnected
from ground.
Loss of local ground
must not affect
communication in the
residual network.
Leakage current at a
disconnected battery.
Node has to sustain the
current that can flow
under this condition. Bus
must remain operational
under this condition.
