Parameters
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.
Node has to sustain the
current that can flow
under this condition. Bus
must remain operational
under this condition.
