Self-adapting current limitation

VBUS = VBAT_max

Input leakage current at the

receiver, inclusive pull-up

resistor as specified

Leakage current LIN recessive

Leakage current at ground loss,

Control unit disconnected from

ground,

Loss of local ground must not

affect communication in the

residual network
