Parameters guaranteed for 7.0 V
Voltage range at the battery level, including the reverse battery diode.
Loss of local ground must not affect communication in the residual network.
Node has to sustain the current that can flow under this condition. The bus must remain operational under this condition.
LIN threshold for a dominant state.
LIN threshold for a recessive state.
This parameter is guaranteed by process monitoring but not production tested.
When an over-temperature shutdown occurs, the LIN transmitter and receiver are in recessive state and INH switched off. This
parameter is tested with a test mode on ATE and characterized at laboratory.
