1. EN, DIR, PWM = high
2. The use of X7R material is recommended
3. For higher values, stability at zero load is not guaranteed
4. Tested during qualification only
5. Value depends on T
6. Tested during characterization only
7. Supplied by charge pump
8. See section
9. Voltage between source-drain of external switching transistors in active case
10. The short-circuit message will never be generated for switch-on time < t
Parameters
Leakage current at
ground loss
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
Center of receiver

Receiver dominant state
Receiver recessive state
Receiver input hysteresis V
Dominant time for
wake-up via LIN-bus
Control Inputs EN1, DIR, PWM, WD, TX
Input low-voltage
threshold
Input high-voltage
threshold
Hysteresis
Pull-down resistor
