blocking of the LIN network by a local ECU the TLE7259G has an integrated power-on reset and undervoltage
detection. In case the supply voltage is dropping below the power on reset level
changes the operation mode to Stand-By mode. In Stand-By mode the output stage of the TLE7259G is disabled
and no communication to the LIN bus is possible. The internal bus termination remains active as well as the INH
pin (see
In Stand-By mode the RxD pin signals the low power supply condition with a logical “High“ Signal. A logical “High“
on the EN pin changes the operation mode back to Normal operation mode.
In case the supply voltage
disables the output and receiver stages. The feature secures the communication on the LIN bus, even if the local
ECU power supply of the TLE7259G drops below the specified operating range. If the power supply reaches a
higher level as the undervoltage level
change only apply if the power supply
