No. 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

threshold
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
