Parameters
At VCC undervoltage
threshold the state
switches back to Pre
Normal Mode
Hysteresis of
undervoltage threshold
Output current limitation V
LIN Bus Driver: Bus Load Conditions:
Load1 (Small): 1 nF, 1 k ; Load2 (Large): 10 nF, 500 ; RRXD = 5 k ; C
10.5, 10.6 and 10.7 Specify the Timing Parameters for Proper Operation at 20 Kbps

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
